Abstract
From norbornane- and norbornene-fused azetidinones 1a and 1b, 1,4-meth anopyrrolo-, 1,4-methanopyrido- and 1,4-methanoazepino[2,1-b]quinazoli nones 6a,b-9a,b were prepared by ring enlargement. Norbornene derivati ves 6b-9b underwent retrodiene decomposition to give pyrrolo-, pyrido- and azepino[1,2-a]pyrimidinones 10-13, respectively.
