Recent Advances in Catalytic Asymmetric Reactions of Thiazolones, Rhodanines and Their Derivatives

AbstractSulfur‐containing skeletons are widely found in natural products, drugs and bioactive compounds. As a direct and efficient access to sulfur‐functionalized carbon stereocenters, the catalytic enantioselective reactions of sulfur‐containing prochiral carbon centers have attracted great attention in the past few years. The review summarizes the chemistry of thiazolones, rhodanines and their derivatives in the context of catalytic enantioselective construction of sulfur‐containing skeletons.magnified image

Direct Catalytic Asymmetric Addition of Acetonitrile to Aldimines.

Despite significant advances in catalytic asymmetric reactions with decent stereocontrol, those using acetonitrile as a pronucleophile are often disregarded due to their low reactivity and insufficient enantioselectivity. Herein we report the resurgence of this reaction in the chemical toolbox with high enantioselectivity (avg. > 95% ee). The combined use of a Ni(II) complex ligated with a chiral biscarbene and tBuOK engages acetonitrile in the catalytic generation of an α-cyanocarbanion and subsequent highly enantioselective addition to aldimines.
