摘要：

The synthesis and isolation of some O-acylisourea derivatives are described. The reaction between coumarin-3-carboxylic acids and diisopropyl- and di-tert-butyl-carbodiimides leads only to coumarin-isourea derivatives except for two reactions which lead, as by-products, also to coumarin-urea derivatives.
