Abstract
Cycloaddition reaction of electron-deficient azides (5a, b) to 2-azabicyclo [2.2.1]hept-5-en-3-one (ABH) (1) was accelerated by high-pressure, leading to a mixture of regioisomeric triazolines (6) in good yields. Then, 6 were in turn, through photolysis and ring opening sequences, converted to 6-azab icyclo[3.1.0]-hexanes (8).
