摘要

Recently, much attention has been paid to the development of new methods for the synthesis of heterocyclic compounds, due to their potential importance in the fields of pharmaceutical and agricultural drugs. The 1-benzopyran ring system constitutes the basic skeleton of a variety of natural compounds that show interesting biological activities 1-2 View all references. The direct synthesis of these compounds based on the reaction of phenols with unsaturated ...
