Enantiodivergent, Catalytic Asymmetric Synthesis of γ-Amino Vinyl Sulfones
摘要:
A set of diversely substituted N-Boc-gamma-amino vinyl sulfones has been prepared by a four-step procedure from readily available, highly enantiopure anti-N-Boc-3-amino-1,2-alkanediols. This new route, which does not depend on the accessibility of alpha-amino acids as starting materials, is noteworthy for its efficiency, for its generality, and for the fact that both enantiomers of a given gamma-amino vinyl sulfone can be obtained with equal ease.

mM, and k2 = 0.015 and 0.010 s-1, respectively). Inhibition of DPP-I by 3d provides only the second example of a cysteine protease which is strongly inhibited by a nitrileanalogue of a specific substrate. Further studies are needed to determine the generality and potential utility of this finding. Compounds 3e, 3f, and 4e exemplify a new class of specific affinity labels for cysteine proteases whose

an acrylate and vinyl sulfone-based chemical series was investigated as promising starting scaffolds against VEEV and as inhibitors of the cysteineprotease domain of VEEV’s nonstructural protein 2 (nsP2). Primary screen and dose response studies were performed to evaluate the potency and cytotoxicity of the compounds. The results provide structural insights into a new class of potent nonpeptidic covalent
