摘要

3-Cyanochromones constitute an important class of intermediates because of their use in the synthesis of anti-allergic substances.'The cyan0 group enhances the dienophilic nature of the carbon-carbon double bond of the cyclic enone system and thus 3-cyanochromones have been extensively used as dienophiles in the synthesis of compounds with selective acetylcholinesterase inhibiting activity? Several methods have been reported for the ...
