Abstract:
X-Ray structure analyses of the inclusion complexes indicated that the high stereo- and enantioselectivities in photocyclization of cyclohex-1-enecarboic acid methyl-phenyl-amide (3), N-methyl, N-{(E)-methylmethacryloyl}anilide (5), N-methyl, N-(methacryloyl)anilide (8), and N-ethyl-N-methylbenzoylformamide (10) are the result of their chiral conformations in the clathrate crystalline environment with the title chiral hosts [(-)-1 and (-)-2, respectively]. The chirality of acrylanilides and benzoylformamide can be indicated by the sign of the torsion angle in the backbone of the molecule, C-N-C(=O)-C and O=C(-Ph)-C(=O)-N, respectively. A partial single-crystal-to-single-crystal transformation of 1 : 1 complex of 10 with (-)-1 was performed by photoirradiation to observe in situ the photoproduct.
