Abstract

The development of chiral catalysts that mediate the asymmetric aldol condensations in a highly stereocontrolled and truly catalytic manner has been a challenging goal in synthetic organic chemistry. Although much fascinating chemistry has been exploited on this problem, which provided excellent methods for chirality transfer from chiral substrates or auxiliaries to prochiral molecules, it has not led to an ultimate means of propagating chirality with a ...
