1,3-dipolar cycloaddition of nitrile oxides to methyl 3-(p-nitrobenzoyloxy)acrylate: Methyl 3-(p-nitrobenzoyloxy)acrylate as a methyl propiolate equivalent with reverse regioselectivity

摘要

3-Aryl-4-methoxycarbonylisoxazoles were prepared from the reaction of a variety of substituted benzonitrile oxides with methyl 3-(p-nitrobenzoyloxy)acrylate in moderate to good yields. [References: 7]
