A Powerful Chiral Counteranion Motif for Asymmetric Catalysis

摘要

Chiral binol-derived phosphoric acids and N-triflyl phosphoramides have been recen introduced as successful motifs for asymmetric Bronsted acid catalysis, particularly for 1 activation of imines and ketones. However, simple aldehydes represent an important 1 challenging group of substrates for organocatalysis. Our research group is currently expori alternative chiral Bronsted acid motifs, focusing on very strong chiral "super Bronsl
