We describe a strategy for intermolecular branched-selective alpha-alkylation of ketones using simple alkenes as the alkylating agents. Enamides derived from isoindolin-1-one provide an excellent directing template for catalytic activation of ketone alpha-positions. High branched selectivity is obtained for both aliphatic and aromatic alkenes using a cationic iridium catalyst. Preliminary mechanistic study favors an Ir-C migratory insertion pathway.

To have a balance between reactivity and selectivity has been a long-standing challenge in multicomponent reactions. In this communication, a carbonylative four-component reaction has been developed. With copper as the catalyst, using ethene including other aliphatic alkenes, alcohols and acetonitrile as the substrates under CO pressure, various desired products were produced in moderate to good yields. The obtained products can be applied in the synthesis of delta-valerolactams. Good functional group tolerance and reaction efficiency can be observed here.

A ruthenium-catalyzed hydrovinylation-type cross-coupling of ynamides and ethylene proceeds via ruthenacyclopentene to give 2-aminobuta-1,3-diene derivatives in a highly regioselective manner. It was also demonstrated that 2-aminobuta-1,3-diene derivatives reacted with various dienophiles or singlet oxygen to give a cyclic enamide derivative.

A series of new (5R,8R,10R)-ergoline derivatives was synthesized, and their antihypertensive and dopaminergic activities were tested in conscious spontaneously hypertensive rats and in rats with unilateral 6- hydroxydopamine-induced lesions of the substantia nigra. (5R,8R,10R)-6- Alkyl-8-ergolinemethanols, prepared from the corresponding ergolinecarboxylates, were converted to the tosylates, which were treated with various five-membered heterocycles containing nitrogen atoms to afford the new ergolines. (5R,8R,10R)-8-(1,2,4-Triazol-1-ylmethyl)-6-methylergoline (4s, maleate: BAM-1110) exhibited potent dopaminergic activity, about 18- fold greater than that of bromocriptine mesylate. (5R,8R,10R)-8-(1,2,4- Triazol-1-ylmethyl)-6-propylergoline (8b, fumarate: BAM-1602) showed extremely potent dopaminergic activity, being about 220 and 1.15 times more active than bromocriptine mesylate and pergolide mesylate, respectively. Several compounds exhibited potent antihypertensive activity. Structure- activity relationships for antihypertensive and dopaminergic activities are discussed.

HPLC of Formula: C3H5NO2, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 497-25-6, molcular formula is C3H5NO2, introducing its new discovery.

Multicomponent reactions (MCRs) represent an ideal organic synthesis tool for the rapid construction of complex molecules due to their step and atom economy. Compared to two-component reactions, the development of new MCRs has been greatly limited during the 170 years since the first MCR was reported. Theoretically, the trapping of an active intermediate generated from two components by a third component could change the traditional two-component reaction pathway, leading to the discovery of MCRs. We report an example of the trapping of a-imino enols generated in situ from 1-sulfonyl-1,2,3-triazoles via a-imino metal carbene species by vinylimine ions using C(2)-substituted indoles and paraformaldehyde as precursors in the presence of a rhodium(II) catalyst. The traditional enol-ketone transformation pathway was suspended by the trapping procedure and efficiently switched to an MCR pathway to produce a-amino-b-indole ketones in moderate to good yields. Unexpectedly, the resulting products and the theoretical density functional theory (DFT) calculation results indicated that the enolic carbon had a stronger nucleophilicity than the well-known traditional enamic carbon in the trapping process. The reaction mechanism was investigated using control experiments and detailed DFT calculations, and the synthetic application of the products was also illustrated. The developed strategy provides a mild and rapid access to a-amino-b-indole ketones and suggests a rationale for the discovery of MCRs by trapping an active intermediate with a third component in a traditional two-component reaction pathway.

Electric Literature of 497-25-6, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments.

Background: Despite being known for their antibacterial activity, the oxazolidines are molecules with wide pharmacological action and may act as anticonvulsants, anti-inflammatory and antineoplasic agents. However, such activities have been poorly explored and only two oxazolidinic derivatives hit the market until now. Therefore, this review covers the main biological activities of oxazolidines, indicating which of the classes and substituents have the best biological results as well as the synthesis methodology used to obtain them. Methods: The search for bibliographic data was made using a question focused on the oxazolidine structure and their respective activities, besides using inclusion/exclusion criteria clearly defined. The selected papers were subjected to qualitative content analysis methodology to be used in this review. Results: The oxazolidines remain excellent candidates for antibacterial, presenting three compounds in clinical testing phase (Radezolide, Cadezolide and Sutezolide), besides being a good candidate as antitubercular agents. Other less explored activities have niches with a great therapeutic potential such as the oxazolidines acting on 5-HT receptors (anticonvulsant) and Zolmitriptan (anti-migraine), and also mefloquine-oxazolidine derivatives which may act as antineoplasic and antitubercular agents. Conclusion: This review summarizes the versatility and great therapeutic potential that oxazolidines can offer, reinforcing the need for further studies and investments for this class of molecules.
