  Synthesis of 17β-estradiol derivatives with n-butyl, n-methyl alkylamide side chain at position 15

  摘要：

  New derivatives of 17-beta-estradiol with N-butyl, N-methyl alkylamide side chains of three different lengths at position 15 have been synthesized from estrone. Compounds 5 and 6 having a shorter alkylamide chain were obtained in eleven steps by introduction of a 15, 16 double bond followed by an 1, 4 addition of alkylcopper reagent and further transformations including hydrolysis, Jones' oxidation, amidation, reduction and cleavage of the protective group. Compound 7 having the longest alkylamide chain was synthesized by chain lengthening (five additional steps) of an intermediate obtained in the course of synthesis of compound 6.
