Azabicyclo Compounds—XI. A study of the fragmentation processes of quinuc‐lidine and some of its derivatives

Organic Mass Spectrometry, 1972
AbstractThe mass spectra of quinuclidine, all the ring position deuterated analogues and some methyl homologues have been measured. Plausible mechanistic interpretations of principal fragment ions are discussed, in the case of quinuclidine, with the help of deuteration in all the ring positions.

5-Aryl-3-azabicyclo[3.2.0]heptan-6-one ketals, compounds with morphine-like analgesic activity.

Journal of medicinal chemistry, 1984
A series of 5-aryl-3-azabicyclo[3.2.0] heptan -6-one ketals 6 were synthesized by hydride reduction of 1-aryl-4, 4-dimethoxy-1,2- cyclobutanedicarboximides 5. Imides 5 were obtained as the sole, regioselective products of the [2 + 2] photocycloaddition of 1,1- dimethoxyethylene to 2- arylmaleimides .
