摘要

2 3 (35%) stituted methylenecyclobutenones have been prepared by this route, 4 but this route cannot be used to prepare 1. The precursor of 1 would have to be an isobenzofuran which would be too reactive to be pyrolyzed under FVP conditions. In this communication we report the synthesis of 1 by a route involving the FVP of 3 4 (benzoy1oxy) methyl) benzofuran (4).
