Abstract
N-Benzyl and (R)-N-(alpha-phenylethyl) nitrones derived from 1-allyl-2-imidazolecarbaldehyde underwent intramolecular cyclo-addition to give predominantly bridged-ring products. namely 5,6,8,9-tetrahydro-6,9-methanoimidazo[2,1-d][1,2,5]oxadiazepine derivatives. Catalytic hydrogenation of the latter furnished both racemic and enantiopure 6,8-functionalised 5,6,7,8-tetrahydro-imidazo[1,2a]pyridines. (C) 2002 Elsevier Science Ltd. All rights reserved.
