Organocatalytic activation of pyruvates toward Michael addition to nitroalkenes: synthesis of γ‐aminobutyric acid (GABA) derivatives

Advanced Synthesis & Catalysis
Despite the significant role of pyruvic acid in biotransformations, the utilization of pyruvates in the field of catalytic asymmetric synthesis has been unexpectedly limited. This statement also applies to enamine catalysis, in which pyruvates seem to be

Synthesis and biological evaluation of substituted pyrrolidines and pyrroles as potential anticancer agents

Archiv der Pharmazie, 2020
A series of polysubstituted pyrrolidines obtained via ruthenium‐catalyzed cascade cyclization of diazo pyruvates and anilines as well as their corresponding pyrrole analogs obtained via dehydration were evaluated for their antiproliferation activities ...
