Asymmetric Total Synthesis and Biological Evaluation of Proapoptotic Natural Myrcene-Derived Cyclohexenyl Chalcones

Based on a bioinspired asymmetric Diels?Alder cycloaddition using a chiral Evans oxazolidinone, the first total synthesis of both enantiomers of two myrcene-derived cyclohexenyl chalcones, fislatifolione and fislatifolic acid, has been carried out. This strategy was also applied to the total synthesis of nicolaiodesin C. These natural products, as well as their synthetic intermediates, were evaluated by in-vitro affinity displacement assays, based on the modulation of Bcl-xL/Bak, Mcl-1/Bid, and Bcl-2-Bim interactions. This study showed that (+)-fislatifolic acid acts as a dual Bcl-xL/Mcl-1 inhibitor with micromolar activity, and that a Weinreb amide intermediate acts as an excellent Mcl-1/Bcl-2 dual inhibitor at the submicromolar level.

Enantioselective Construction of Acyclic Quaternary Carbon Stereocenters: Palladium-Catalyzed Decarboxylative Allylic Alkylation of Fully Substituted Amide Enolates

We report a divergent and modular protocol for the preparation of acyclic molecular frameworks containing newly created quaternary carbon stereocenters. Central to this approach is a sequence composed of a (1) regioselective and -retentive preparation of allyloxycarbonyl-trapped fully substituted stereodefined amide enolates and of a (2) enantioselective palladium-catalyzed decarboxylative allylic alkylation reaction using a novel bisphosphine ligand.

Structure-based design, synthesis, and biological evaluation of irreversible human rhinovirus 3C protease inhibitors. 1. Michael acceptor structre-activity studies

The structure-based design, chemical synthesis, and biological evaluation of peptide-derived human rhinovirus (HRV) 3C protease (3CP) inhibitors are described. These compounds incorporate various Michael acceptor moieties and are shown to irreversibly bind to HRV serotype 14 3CP with inhibition activities (k(obs)/[I]) ranging from 100 to 600 000 M-1 s- 1. These inhibitors are also shown to exhibit antiviral activity when tested against HRV-14-infected H1-HeLa cells with EC50’s approaching 0.50 muM. Extensive structure-activity relationships developed by Michael acceptor alteration are reported along with the evaluation of several compounds against HRV serotypes other than 14.

Rational design of highly effective asymmetric Diels-Alder catalysts bearing 4,4-sulfonamidomethyl groups

(Chemical Equation Presented) The rational design of bis(oxazoline)- copper(II) catalysts based on postulated intramolecular secondary n-cation interaction for the highly enantioselective Diels-Alder reaction is presented. A theoretical calculation suggested that the n electrons of the 4,4-sulfonamidomethyl groups successfully interact with the Cu(II) cation and that the counteranions with protons of sulfonamido groups. These secondary interactions might be essential for the high catalytic activity, the broad range of substrates, and the high level of induction of the enantioselectivity.

Extensive dataset for oxidative degradation of ethanolamine at 55-75 c and oxygen concentrations from 6 to 98%

Post combustion CO2 capture using amines as chemical absorbents is a relatively mature technology. Rate of reaction and desorption energy demand are normally prime criteria for evaluation of new solvents while degradation and corrosion studies are often postponed. However, degradation and corrosion are in many cases showstoppers and should be considered at an early stage. In this work, a systematic study has been conducted on oxidative degradation of 30 wt% ethanolamine (MEA) for oxygen concentrations: 6, 21, 49 and 98% and temperatures: 55, 65 and 75 C. The formation of ten primary degradation compounds (acids, ammonia and alkyl amines) and seven secondary degradation compounds (HEGly, OZD, HEPO, HEF, HEA, HEI and BHEOX was monitored as function of time over a period of 3-6 weeks. The full comprehensive data set is available in the supplementary information for development of models describing the degradation behavior. Suggested mechanisms for formation of seven secondary degradation compounds; HEGly, HEPO, OZD, HEF, HEA, BHEOX and HEI from literature were compiled and discussed in view of the experimental results to suggest pathways which are more likely than others. The rate of MEA degradation increases with increasing temperature and oxygen concentration. The overall nitrogen balances were closed within 83-97%; the higher deviations observed at the highest temperature, 75 C. HEF, HEI and ammonia were the degradation compounds that most significantly contributed to the nitrogen balance in most experiments. However, at 6% O2 content, HEGly was the major nitrogen containing degradation compound identified. Formate was found to be the major anionic compound in all experiments. HEGly formation was found to be independent on O2 partial pressure, but this may not be true for the further reaction of HEGly. The results suggests OZD formation to be oxygen dependent. However, only one mechanism is so far suggested for an oxygen dependent pathway. Both OZD and HEPO concentrations increase with oxygen concentration. Separate laboratory experiments at constant temperature (55-75 C) do not capture the HEPO formation seen in pilot plant samples indicating that higher temperatures and/or temperature cycles are necessary. The results clearly show that performing accelerated degradation tests with 98% oxygen cannot easily be extrapolated to what happens at 6% oxygen, and therefore may not be representative for the situation in an industrial plant both with regard to rates of formation and products formed.

A refined synthesis of enantiomerically pure 2-aminocyclobutanecarboxylic acids

The synthesis of enantiomerically pure 2-aminocyclobutanecarboxylic acids has been refined to improve both the efficiency and the simplicity. These improvements provide a shorter and easier access to the racemic cis-cyclobutane beta-amino acid core. Derivatization of this material with a chiral non-racemic oxazolidin-2-one allows easy diastereoisomeric separation and presents the advantage of allowing the non-destructive cleavage of the chiral auxiliary either by hydrolysis or by ammonolysis, thus providing an efficacious access to N-protected derivatives of all four stereoisomers of Boc-2-aminocyclobutanecarboxylic acid.

Highly Selective Syn Addition of 1,3-Diones to Internal Ynamides Catalyzed by Zinc Iodide

1,3-Diones are already established as nucleophiles to perform additions to ynamides; the highly selective hydroalkoxylation of internal ynamides is now described. Several catalytic systems have been compared to perform this transformation, including transition-metal-based catalysts and Lewis acids. ZnI2 was found to be both very active and highly selective providing only E adducts through a syn addition. Investigation of the scope and limitations showed that this catalyst was compatible with various functional groups. In addition to seventeen examples of ynamide hydroalkoxylation, one example of ynamide hydroarylation is reported.
