The Bu3SnH mediated cyclisation of various N-acryloxy-2-amino-2-cycloh
exenones was explored. This predominantly gave rise to bicyclic lactam
s but the reaction mechanism was shown to depend upon the substitution
of the amide double bond. Preliminary studies targeted towards the pr
eparation of bicyclic lactones are also reported. (C) 1998 Elsevier Sc
