摘要：
A convenient two-step approach for the syntheses of 3-aryl-3,4-dihydroisocoumarins (13-17) including some naturally occurring 3-aryl-8-hydroxy-3,4-dihydroisocoumarins (1,2) and lunularic acid derivatives (18-21) is described from 2-formylbenzoic acids (4,5). AlC13 has been used for the first time as a catalyst for the conversion of stilbene-2-carboxylic acids (11, 12) to the corresponding 3-aryl-8-hydroxy-3, 4-dihydroisocoumafins (1 and 2) in high yields.
