Abstract

A convenient method is reported for the synthesis of 34 novel tricyclic and tetracyclic cage-like lactams in high to excellent yields. The method involves treatment of easily available exo-2,3-epoxy(or Ts-aziridino)bicyclo[2.2.1]heptan-endo-5,6-dicarboximides by Grignard reagents, their N-analogues, or phenyl lithium in tetrahydrofuran. In silico screening of biological activity spectrum showed high probability levels of glyceryl-ether monooxygenase inhibitory, testosterone 17β-dehydrogenase (NADP+) inhibitory, bilirubin oxidase inhibitory, and anti-ischemic activity for tetracyclic derivatives.
