Cyclization of 4-(3'-butenyl)azetidin-2-one, 2 initiated by electrophilic reagents such as 12, Hg(OAc)2 results in the formation of bicyclic B-lactams having the carbopenam ring skeleton. Reaction of gwith Br2 results in simple addition of Br2 to the double bond, while PhSBr gives a mixture of cycli
