Abstract
Intermolecular 1,3-dipolar cycloadditions of 2-(2-phenylethenyl) pyridinium N-ylides (3a-d) with electron-deficient alkenes (5a-d) were carried out se lectively in the presence of tetrakis-pyridine cobalt(II) dichromate to yie ld 5-(2-phenylethenyl)indolizines (6a-j) in moderate yields (48-63%).
