  摘要：

  The syntheses of ethyl (E)-4-[(2,3-dihydro-2,2,4,4-tetramethyl-2H-1-benzo[b]thiopyran-6-yl)-1-propenyl]-2-methylbenzoate acid (1) and (E)-4- [(2,3-dihydro-2,2,4,4-tetramethyl-2H-1-benzo[b]thiopyran-6-yl)-l-pro-penyl]-2-methylbenzoic acid (2) haue been achieved. In comparison to ester 1, acid 2 exhibited greater efficacy in activating RARalpha, RARbeta, and RARgamma as well as greater potency in activating RARalpha and RARbeta. Interestingly, both the ester 1 and acid 2 exhibited nearly equal polency in activating RARgamma. Both compounds also inditced tissue transglutaininase (TGase) activity approximately 50% of the level induced by trans-retinoic acid. An X-ray diffraction analysis of (E)-2 revealed the aryl rings as nearly orthogonal [74.0(2)degrees] and a torsional angle of 46.5(2)degrees between the thiochroman group and the propenyl group. Conjugation between. such groups may not be a stringent requirement for receptor activation.
