Abstract
Condensation of 10b-methyl-1,5,6,10b-tetrahydroimidazo[2,1-a]isoquinolin-2(3H)-one with aromatic aldehydes affords 10b-(2-arylethenyl)-1,5,6,10b-tetrahydroimidazo[2,1-a]isoquinolin-2(3H)-one derivatives, which on heating in ethanol easily transform to 2,3,5,6-tetrahydropyrrolo[2,1-a]isoquinoline-3-carboxamides.
