Abstract
A series of diversely substituted 2H-2-benzazepine-1,3-diones were efficiently prepared from the unsaturated precursors, N-acyl-o-vinylbenzamides, through a ring-closing metathesis reaction. The parent compounds were easily obtained from the appropriate o-vinylbenzoic acids.
Key words
fused-ring systems - acylation - ring closure - metathesis - imides
