, p. 1180 - 1185 (2007/10/02)

Carbonyl- and nitrile-stabilised pyridinium and cyclic azonium methylides condense with chalcones to form tetrahydroindolizines and analogous fused pyrrolidines.The stereochemistry is illuminated by 13C and 1H n.m.r. spectroscopy.Several incorrect literature structures are rectified.
