Rhodium(II)-catalyzed dipolar cycloaddition of cyclic diazodicarbonyl compounds with alpha,beta-unsaturated esters. Synthesis of dihydrofurans

摘要

An efficient synthesis of dihydrofurans is achieved by rhodium-catalyzed dipolar cycloaddition of cyclic diazodicarbonyl compounds with alpha,beta-unsaturated esters. [References: 9]
