Asymmetric construction of quaternary stereocenters by direct conjugate addition of oxindoles to enone
摘要:
Chiral cinchona-based primary amine A was found to catalyze the asymmetric direct conjugate addition of prochiral 3-oxindoles with enones to afford 3 3-disubstituted oxindoles in good yields moderate to high diastereoselectivities and excellent enantioselectivities (C) 2010 Elsevier Ltd All rights reserved
