Abstract
Cycloadducts (6-9) were synthesised from isomunchnone derivatives of ( 5R)- and (5S)-phenyloxazin-3-one by rhodium(II)-catalysed decompositio n of alpha-diazocompounds (3a-c). Additions to various carbon-carbon d ipolarophiles proceeded with high endo/exo-selectivities and moderate diastereofacial selectivities. (C) 1997 Elsevier Science Ltd.
