T1 - (R,R)-( - )-trans-1,4-Dioxaspiro[4,4]nonane-2,3-diylbis(diphenylmethanol)- N-allyl-N-propyl-3-oxocyclohexene-1-carboxamide (2/1)

N2 - The enantioselective intramolecular photocyclization reaction of N-allyl-N-R-3-oxo-1-cyclohexenecarboxamides in inclusion crystals was studied. The products obtained were tricyclic compounds, as the results of a [2+2]-photoreaction in the guest molecule, except for that with R = nPr, which gave the spiro β-lactam (A), not the tricyclic compound (B). The crystal structure of the given compound is determined to investigate the conformation of the amide (R = nPr). It was observed that molecular structure of the amide compound is same as that observed in the inclusion compound with the corresponding six-membered ring host, differing only in the size of the cycloalkane ring.
