摘要：

Reactions of the ylide 1 and o-hydroxybenzaldehydes 2a-c gave, depending on the reaction conditions, 3-(2-hydroxyphenyl)coumarin derivatives 5a-c, 3-(2-hydroxybenzylidene)benzo[b]furan-2(3H)-one 4 and, in one step, the coumestan derivative 6. Reaction of the ylide 11 with 2a resulted in the coumarin derivative 1 3 and the coumestan derivative 14.
