The title heterocycles rearrange into a mixture of diastereoisomeric hexahydro-1(2H)-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 – (2α, 3α, 3aα, 6aα) is also reported.
