title: Chiral Diphenylprolinol TES ether promoted conjugate addition-aldol-dehydration reactions between alpha,beta-unsaturated aldehydes and 2-N-protected amino benzaldehydes.
abstract: 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]
