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.
开发了过氧化二月桂酰（DLP）促进的炔酸酯与黄原酸酯的碳环化反应，以中等至良好的产率得到了一系列4-芳基-3-（β-羰基）香豆素。炔酸酯的双官能化是在无金属条件下通过自由基加成/环化过程实现的。
