Abstract
Pyridinium imides 3-5 and 8 are obtained as crystalline solids from th e reaction of 3-acetoxyaminoquinazolinones 2 and 10 with the correspon ding pyridines; barriers to rotation around each of the N-N bonds in 3 have been measured by NMR spectroscopy, and the imides 3-5 react both with styrene and with diethyl fumarate to give the corresponding azir idines.
