摘要
Compounds with the 1-azabicyclo[4.3.0]nonan-2-one nucleus have been prepared with methyl and isobutyl groups at C-6. The synthetic sequence was: geminal acylation to produce a but-2-enylcyclopentane-1,3-dione derivative, treatment with O-mesitylenesulfonylhydroxylamine and then Beckmann rearrangement with BF3.Et2O and cyclization of the amidic nitrogen onto the terminal double bond. In addition, the results of exploratory reactions are presented.
