## Abstract The piperidine ring in the title compound is in the chair conformation, whereas the diketopiperazine ring has a boat form. The benzyl group is axially positioned and folded above the diketopiperazine ring. No dimerisation is observed.
Irradiation of 2,4-cyclohexadienones (L) usually produces ketenes. Most commonly, these ketenes either thermally recyclize to dienone or, in the presence of nucleophiles, react to form open-chain unsaturated acids or their derivatives.lm4 In special cases, however, the ketene may thermally cyclize t
