The title heterocycles rearrange into a mixture of diastereomeric hexahydro-1(H)-pentalenone derivatives, which undergo nucleophilic eliminative ring fission by methanol to give 1-amino-2-nitroalkylated cyclopentancarboxylic esters.The X-ray structure determination of hexahydro-2-methyl-2-nitro-3-phenyl-6a-(1-piperidinyl)-1(2H)-pentalenone is also reported.
