  A Practical Synthesis of 14-epi-19-nor-1α,25-Dihydroxyvitamin D3 Analogues and Their A-ring Epimers

  摘要：

  A practical synthesis of (2S,3aS,4aS)-2-tert-butyldimethylsilyloxybicyclo[3.1.0]hexane-3a-carbaldehyde (14a) and diastereoisomers, starting from all-cis methyl 3,5-dihydroxy-1-cyclohexanecarboxylate (24) is described. Coupling with appropriate cis-hydrindanes produces the title compounds. TX 522, a member of this series, is currently in phase II clinical studies for the treatment of psoriasis. The key step involves the coupling of 14 and 16 with the respective cis-hydrindanes 9 and 7.

  Asymmetrization of all-cis-3,5-dihydroxy-1-(methoxycarbonyl)cyclohexane and of the 4-methyl and 4-ethyl substituted homologues

  摘要：

  Enantiomerically pure mono acylated derivatives of cis,cis-3, 5-dihydroxy-1-(methoxycarbonyl)cyclohexane 1, all-cis-3,5-dihydroxy-4-methyl-1-(methoxycarbonyl)cyclohexane 2 and all-cis-3,5-dihydroxy-4-ethyl-1-(methoxycarbonyl)cyclohexane 3 were obtained upon lipase catalyzed asymmetrization. PPL-catalyzed transesterification of 1 with vinyl acetate led in high yield to the (S)-monoacetate (+)-13. With substrates 2 and 3 this process was slower and gave the (R)-monoacetates (-)-14 and (-)-15; the best results were obtained with SAM II lipase. On the other hand, enantiotoposelective hydrolysis of their diacetates and especially dibutyrates gave useful results only for the 4-substituted substrates and produced the (S)-monoesters.
