Expedient Synthesis of Highly Substituted Fused Heterocoumarins

Selles,Mueller

, p. 277 - 279 (2004)

(Matrix presented) Highly substituted fused coumarins can be prepared in two steps starting from the appropriate boronic acids and enol triflates. The synthesis of fused pyrano[2,3-d]pyrimidin-7-one (1) is a key example to demonstrate the potential of the method in the elaboration of new coumarin scaffolds.
