Abstract
The cyclisation of diene-conjugated carbonyl ylides of the general typ e 2, in which the alpha,beta;gamma,delta diene function is formed by a benzene ring and either a thiophene or pyridine ring provides a new r oute to some hetero-fused dihydrobenzooxepines. The oxirane precursors for the carbonyl ylides were synthesised in a two-step scheme from re adily available reactants.
