  Synthesis of 13,14-secotestosterone derivatives

  摘要：

  A number of testosterone analogs with a 13,14-secosteroidal fragment have been prepared from (13S)-13-iodo-6beta-methoxy-3alpha, 5-cyclo-13,14-seco-5alpha-androstan-14,17-dione. The key steps involved stereoselective deiodination of the starting compound with triphenylphosphine and selective protection of the 17-keto group with trimethylsilylcyanide. Removal of iodine at C-13 proceeded with inversion of the configuration at C-13, which has been established by X-ray crystallography. 13,14-Secotestosterone analogues substituted and non-substituted at C-14 have been prepared. The obtained compounds containing flexible CD ring fragments are of great interest for comparative studies in biological tests together with testosterone and other steroids with a rigid tetracyclic skeleton.
