One-pot synthesis of alkynylthiocyanates by phase-transfer reagent

Thiocyano-group widely exist in natural products and drug structures. A novel one-pot synthesis of alkynylthiocyanates from terminal alkynes, [hydroxy(tosyloxy)iodo]benzene and potassium thiocyanate by phase-transfer reagent involving the hypervalent iodine intermediates in transition metal-free conditions was developed. The internal alkynylthiocyanates could be used to synthesize some important compounds such as 5-thiocyanato-1,2,3-triazoles and (Z)-alpha-thiocyanato-vinyl trifluoromethanesulfonate.

Total synthesis of (+)-suaveolindole: Establishment of its absolute configuration

This communication describes two approaches toward the total synthesis of (+)-suaveolindole. The initial strategy uses a 6-exo-Heck cyclization to generate a transient sp3 carbopalladate. This intermediate was successfully coupled with an indole 3-stannane to assemble the majority of the carbon framework of the natural product. However, due to problems described herein, this interesting route was not viable. To reach our target, lessons learned from the first strategy directed us to develop a significant extension of the Ireland ester enolate rearrangement in which the tetra-substituted isopropylidene group and the alpha-disposed carboxymethyl function are introduced in a single event. This key reaction enables a remarkably concise inaugural synthesis of (+)-suaveolindole. Copyright

Rational Design of Highly Diastereoselective, Organic Base-Catalyzed, Room-Temperature Michael Addition Reactions

Via the rational design of a single-preferred transition state, stabilized by electron donor – acceptor-type attractive interactions, structural and geometric requirements for the corresponding starting compounds have been determined. The Ni(II) complex of the Schiff base of glycine with o-[N-alpha-picolylamino]acetophenone, as a nucleophilic glycine equivalent, and N-(trans-enoyl)oxazolidin-2-ones, as derivatives of an alpha,beta-unsaturated carboxylic acid, were found to be the substrates of choice featuring geometric/conformational homogeneity and high reactivity. The corresponding Michael addition reactions were found to proceed at room temperature in the presence of catalytic amounts of DBU to afford quantitatively the addition products with virtually complete diastereoselectivity. Acidic decomposition of the products followed by treatment of the reaction mixture with NH4OH gave rise to the diastereomerically pure 3-substituted pyroglutamic acids.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 497-25-6 is helpful to your research. Related Products of 497-25-6

Recommendations for approaches to meticillin-resistant staphylococcal infections of small animals: diagnosis, therapeutic considerations and preventative measures.: Clinical Consensus Guidelines of the World Association for Veterinary Dermatology

Background: Multiple drug resistance (MDR) in staphylococci, including resistance to the semi-synthetic penicillinase-resistant penicillins such as meticillin, is a problem of global proportions that presents serious challenges to the successful treatment of staphylococcal infections of companion animals. Objectives: The objective of this document is to provide harmonized recommendations for the diagnosis, prevention and treatment of meticillin-resistant staphylococcal infections in dogs and cats. Methods: The authors served as a Guideline Panel?(GP) and reviewed the literature available prior to September 2016. The GP prepared a detailed literature review and made recommendations on selected topics. The World Association of Veterinary Dermatology (WAVD) provided guidance and oversight for this process. A draft of the document was presented at the 8th World Congress of Veterinary Dermatology (May 2016) and was then made available via the World Wide Web to the member organizations of the WAVD for a period of three?months. Comments were solicited and posted to the GP electronically. Responses were incorporated by the GP into the final document. Conclusions: Adherence to guidelines for the diagnosis, laboratory reporting, judicious therapy (including restriction of use policies for certain antimicrobial drugs), personal hygiene, and environmental cleaning and disinfection may help to mitigate the progressive development and dissemination of MDR staphylococci.

New syntheses of the C,D-ring pyrromethenones of phytochrome and phycocyanin

Pyrromethenone 7, the C,D-ring segment of phytochrome (Pr, 4), has been prepared in an efficient fashion employing three new strategies. Each of these has potential advantages for the synthesis of labeled material. Our first approach is related to the Gossauer synthesis, with the difference that strong alkali is avoided in the condensation of the C- and D-ring components 8 and 17. The key silyloxypyrrole 17 was readily prepared on multigram scales beginning with inexpensive butyrolactone (10). A second synthesis began with 2-acetylbutyrolactone (41). The key steps involved conversion of 41 to the Z-enoltriflate 42, followed by Pd(0)-catalyzed coupling with trimethylsilylacetylene, p-chlorophenylselenide ring opening, and finally, amidation to afford the ring-D synthon 45 having the proper geometry and oxidation state for conversion to 7. Sonogashira coupling of 45 with the iodopyrrole 22, followed by oxidative elimination, and F- -induced 5-exo-dig cyclization of the resultant pyrroloalkyne 47, then completed the synthesis. In similar fashion, we have also prepared pyrromethenone 6, the C,D-ring segment of phycocyanin (2).

Study of the MEA degradation in a CO2 capture process based on partial oxy-combustion approach

Partial oxy-combustion is a novel approach for CO2 capture that can be applied to mitigate the CO2 emissions from stationary sources, particularly in fossil-fuels power plants. Some benefits have been identified related to the highly CO2 concentrated flue derived from the application of this technology. The hybrid process combining oxy-combustion with post-combustion approach can theoretically lead to around 25% decrease of the overall energy consumption compared with oxy-combustion process. Improvements of the overall CO2 capture process are mainly focused on CO2 chemical absorption stage. Therefore, the evaluation of the solvent behaviour under these new operating is required to verify the strengths of partial oxy-combustion as a promising CCS technology. In this work, the degradation of a conventional solvent ? MEA 30?wt% ? was studied under rich CO2 environments at typical operating conditions of CO2 absorption. The degradation tests were performed in a semi-batch rig. Variations on key absorption parameters such as temperature and O2 concentration in the flue gas were also studied. MEA losses were determined during the experiments and the most relevant degradation compounds were identified. In this respect, ammonia emissions from the exit gas were measured using a 0.1N sulphuric acid to recovery the ammonia leaving the semi-batch rig. Results from this work concluded that the use of a higher CO2 concentrated flue gas reduced the MEA degradation at absorber conditions. In particular, a 60%v/v CO2 the flue gas reduced up to 50% of MEA losses compared with post-combustion conditions (15%v/v CO2). However, the MEA losses reduction is limited at elevated temperatures. NH3 emissions were also reduced of about 75% when high CO2 concentration were used. This work concluded that partial oxy-combustion technology can substantially reduce the MEA degradation at absorption conditions and thereby this novel CCS approach may become competitive respect to post-combustion.
