Formation of pyridin-4(1H)-one versus 1H-azepin-4(7H)-one by treatment of 4-tert-butyldimethylsilyloxy-2-amino-1-aza-bicyclo[4.1.0]hept-3-enes with tetrabutylammonium fluoride

Cycloadducts 3 and 4 were treated with tetrabutylammonium fluoride and rapidly suffer cleavage on the three-membered ring to form either pyridin-4(1H)-one or 1H-azepin-4(7H)-one. When R1 is an oxycarbonyl or a 2-pyridyl group and R2
