Cycloadducts (6-9) were synthesised from isomunchnone derivatives of (5R)- and (5S)-phenyloxazin-3-one by rhodium(II)-catalysed decomposition of α-diazocompounds (3a-c). Additions to various carbon-carbon dipolarophiles proceeded with high endo/exo-selectivities and moderate diastereofacial selectivities.
