摘要：

An easy preparation of new 4-alkoxycarbonyl angular and linear pyranocoumarins starting from 4-[(1,1-dimethyl-2-propynyl)oxy]phenol and their transformation to the known coumarins xanthyletin, 8,8-dimethylpyrano[3,2 f]chromen-3(8H)-one and 7,7-dimethylpyrano[2,3-g]chromen-2(7H)-one is described.
