Abstract

The dilauroyl peroxide (DLP)-promoted carboannulation of alkynoates with xanthates was developed, affording a series of 4-aryl-3-(β-carbonyl) coumarins in moderate to good yields. The difunctionalization of alkynoates was achieved via a radical addition/cyclization process under metal-free conditions.
