ChemInform Abstract: Diastereoselective Mukaiyama Aldol Reaction of (N-Alkyl) Isatins with 2-(Trimethylsilyloxy)furan by Using Lanthanum Triflate.
摘要：
An efficient vinylogous Mukaiyama aldol reaction (VMAR) of 2-(trimethylsilyloxy)furan with various (-alkyl)isatins is described in the presence of lanthanum(III) triflates (5 mol %). The reaction proceeds rapidly and affords the corresponding 3-hydroxy-(5-oxo-2,5-dihydrofuran-2-yl)indolin-2-one in high yields with good diastereoselectivities (erythroGraphical abstract
