One-pot synthesis of 3-oxo-3,4-dihydroquinoxalines bearing a sulfonamide or an amide group.

[摘要]：A three-component reaction for the synthesis of 3,4-dihydroquinoxalines bearing a sulfonamide or an amide group is described. Intermediate dihydroquinoxalines, derived from the addn. of 1,2-phenylenediamine to acetylenedicarboxylates, possess enamine character, and react with arylsulfonyl isocyanates to produce the title compds.
