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
