Ytterbium triflate-catalyzed reactions of imines with a chiral non-racemic silyloxypyrrole
摘要:
In the presence of a catalytic amount of ytterbium triflate the reactions of various aromatic imines with a chiral non-racemic silyloxypyrrole proceeded smoothly to afford the corresponding aldol-type adducts in go od yields and diastereoselectivities.
