  Synthesis and some reactions of 6-bromoandrogens: Potential affinity ligand and inactivator of estrogen synthetase

  摘要：

  The synthesis of epimeric 6-bromo-4-androstene-3,17-dione (1a and 1b), 6-bromotestosterone (2a and 2b) and its acetate (3a and 3b), and 6-bromo-16 alpha-acetoxy-4-androstene-3,17-dione (5a and 5b), and 6 beta-bromo-16 alpha-hydroxy-4-androstene-3,17-dione (4) is described. The interconversions among compounds 1, 2, and 3 are also studied. The 6 beta-isomer (1b, 2b, and 3b) was epimerized to the 6 alpha-isomer (1a, 2a and 3a) in carbon tetrachloride or chloroform-methanol (9:1) and the 6 alpha-isomer was isolated by fractional crystallization from the epimeric mixture. 6 alpha-Bromo isomer 1a was also epimerized back to 6 beta-bromo isomer 1b in chloroform-methanol (9:1). Two polymorphic forms of 6 beta-bromotestosterone acetate (3b) were isolated (mp. 114--117 degrees and 138--141 degrees). The 6 beta-bromo isomers were found to be unstable in methanol and decomposed to give 5 alpha-androstane-3,6-dione derivative (6). The results of irreversible inactivation of human placental androgen aromatase with some of these 6-bromoandrogens are discussed.

  A synthesis of the enantiomeric tetrahydro-PGA1 analogue 48 is described. In addition the homoacid 50, its pentanor analogue 39 and its epimer 51, the 6-deoxy compounds 13 and 16 as well as the lactones 14, 53, 56 and 68 were prepared as compounds closely related to 48. Simple androstane derivatives served as starting materials for the syntheses. Key intermediates were 4, 32 and 63.
