Silver acetate-catalysed asymmetric 1,3-dipolar cycloadditions of imines and chiral acrylamides
摘要:
N-Metallated azomethine ylides were generated by the reaction of arylidene glycine imines with AgOAc and triethylamine. These azomethine ylides undergo cycloaddition to chiral acrylamides with excellent diastereoselectivity. The configuration of two of the cycloadducts was confirmed by X-ray crystallography.

N-Metallated azomethine ylides 5 were generated by the reaction of arylidene glycine imines 1 with AgOAc and triethylamine. These azomethine ylides undergo cycloaddition to chiral acrylamides 2 with excellent diastereoselectivity. The configuration of two of the cycloadducts (3a 1 and 3c 1 ) has been confirmed by X-ray crystallography.
