Diastereoselective synthesis of trans-2,3-dihydrofuro[3,2-c]coumarins by MgO nanoparticles under ultrasonic irradiation
MgO nanoparticles have been used as an efficient catalyst for the diastereoselective preparation of trans-2-benzoyl-3-(aryl)-2H-furo[3,2-c]chromen-4(3H)-ones by the multi-component reaction of 2,4â²-dibromoacetophenone, pyridine, benzaldehydes and 4-hydroxycoumarin under ultrasonic irradiation.
