Hydride adducts of dinitroquinolines in multicomponent Mannich reaction

Abstract

Dinitro derivatives of 8-oxyquinoline, 8-oxyquinaldine, and 3,4-dihydroquinolin-2-one when reacted with NaBH4 form hydride σH-adducts that are involved into a multicomponent Mannich reaction affording pyridoazabicyclo[3.3.1]nonane.
