摘要

In the course of the synthesis of new heterocyclic derivatives of biological interest,' aryloxopropionic acids 1 were required as potential starting materials for new indanones? cyclopentafuranones3 and cyclopentathiophenones. 4 It is well knowd that malonyl chloride itself or its derivatives condense under the conditions of the Friedel-Crafts reaction with aromatic rings to give such diverse products as monoketones 2, diketones 3 or fused ...
