摘要

A conjugate addition-aldol-dehydration reaction of alpha,beta-unsaturated aldehydes with 2-N-protected amino benzaldehydes has been developed. The process is promoted by (S)-diphenylprolinol TES ether to afford synthetically useful 1,2-dihydroquinolines in high enantioselectivities with good yields. [reaction: see text]
