instead of the expected bicyclic systems 1,5-diazabicyclo[3.2.1]octan-6-one 9 and 3-aryl-1,5-diazabicyclo[3.3.0]octane-2-one 10. The synthesis of two representatives of bicycles 10 (10a,b) proceeded in the reaction of unsubstituted 1,5-diazabicycle[3.1.0]hexane 8a, accordingly, with diphenylketene 1a in benzene at 20 °C and with 4-chlorophenylketene 1b in toluene at 60-110 °C.
