Synthesis and Acylation of Novel Azacrownophanes Containing Fused Piperidin-4-one SubunitAzacrownophanes containing fused piperidin-4-one fragment were successfully prepared through

Substituted and fused spiro[benzo-2-azepine-3,1′-cyclohexanes]5-Methyl-4,5-dihydro-3H-spiro[benzo-2-azepine-3,1′-cyclohexane] N-oxide was rear- ranged into 5

Rac-(1S*,4aS*,8aS*)-4a-Hydroxy-2- methylperhydrospiro[isoquinoline-4,1′-cyclohexan]-2′-one. The cyclohexane and piperidine rings within the perhydroisoquinoline are trans-trans fused. The N atom has a
