Exploratory photochemical studies with N-phthaloyl derivatives of glutamic
acid, aspartic acid, serine, threonine and analogous carboxylic acids and a
lcohols have been conducted to determine the generality of azomethine ylide
forming decarboxylation and retro-aldol fragmentation reactions. Preferenc
es in the competition between these excited state reaction pathways have be
en determined by studies with phthalimides which contain both alpha-amino a
cid and beta-aminoethanol groups. (C) 1999 Elsevier Science Ltd. All rights
