‘One-pot’ Synthesis of Dihydrobenzo[4,5][1,3]oxazino[2,3-a] isoquinolines via a Silver(I)-Catalyzed Cascade Approach

Abstract

An efficient approach for the synthesis of biologically interesting fused tetracyclic isoquinolines in high yields and with a broad substrate scope has been developed. The strategy features an AgNO3 catalyzed ‘one-pot’ cascade process involving formation of two new C–N bonds and one new C–O bond.
