摘要：

The oxidation of α-benzoyl-o-hydroxyacetophenones (3a-d) using iodobenzene diacetate in methanolic potassium hydroxide provides a new direct method for the synthesis of 2-benzoylcoumaran-3~ones (4a-c) in good yields. The formation of 4a-d is explained by neighbouring group participation. © 1990, Taylor & Francis Group, LLC. All rights reserved.
