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.
