Modifications based on coumarins. II. Synthesis ofα-monoglycerides of karatavic and galbanic acids and their phosphates

The synthesis has been performed of α-monoglyceride derivatives of coumarins — karatavic and galbanic acids and their modified derivatives — phosphates. The structures of the compounds have been confirmed by IR, UV, PMR, and13C and31P NMR spectroscopies.
