  Vitamin D (calciferol) and its analogs. 40. 1.alpha.,25-Dihydroxyprevitamin D3: synthesis of the 9,14,19,19,19-pentadeuterio derivative and a kinetic study of its [1,7]-sigmatropic shift to 1.alpha.,25-dihydroxyvitamin D3

  摘要：

  The hormonally active steroid 1-alpha, 25-dihydroxyvitamin D3 (3) exists in equilibrium with its previtamin form 5. In an attempt to further understand the significance of this previtamin and previtamin D's in general, the pentadeuterio analogue of 5 was synthesized. Accordingly, 9, 14, 19, 19, 19-pentadeuterio-1-alpha, 25-dihydroxyprevitamin D3 (6) was prepared from the readily available, optically active synthons (S)-(+)-carvone (10) and the Inhoffen-Lythgoe diol (9). A general method was developed to regioselectively deuteriate beta-methyl-alpha,beta-unsaturated aldehydes via their Schiff bases and was used in the synthesis to convert aldehyde 16a to its deuteriated analogue 16b. Thermolysis of 6 afforded 9, 9, 14, 19, 19-pentadeuterio-1-alpha,25-dihydroxyvitamin D3 (24). A kinetic investigation of the [1, 7]-sigmatropic hydrogen (deuterium) shifts which convert previtams 5 and 6 to vitamins 3 and 24, respectively, revealed that at 25-degrees-C the process proceeds with a relatively normal primary kinetic isotope effect, k(H)/k(D), of 5.5.

  series of analogs of 1,25-dihydroxyvitamin D3, the hormonally active metabolite of vitamin D3, characterised by the presence of a trans-fused decalin CD-ring system, possesses surprising biological activities in combination with specific structural modifications in the flexible parts of the molecule, when compared with the natural hydrindane derivatives. (1) A large difference in biological activity is observed
