摘要：

This contribution describes a regioselective cyclization of hypervalent iodine reagents (HIR) with propiolic acids in the presence of a rhodium catalyst. The mild decarboxylation can tolerate a wide range of groups and generates 4H-furo[3,2-c] chro-men-4-one derivatives in good isolated yields.
