Synthesis of furo[3,2- c ]coumarin from the reaction of 3-halochromone and 2-aminochromone; 2-aminochromone as a masked 4-hydroxycoumarin

Synthesis of 2-(2-hydroxybenzoyl)-4H-furo[3,2-c]chromen-4-one has been accomplished by the reaction of 3-halochromone with 2-aminochromone. In this reaction, 2-aminochromone acts as a masked 4-hydr...
