Synthesis of 5β,17α-19-norpregn-20-yne-3β,17-diol and of 5β,17α-19-norpregn-20-yne-3α,17-diol, human metabolites of norethindrone
摘要:
A convenient synthesis of both 5-beta,17-alpha-19-norpregn-20-yne-3-beta,17-diol (1) and 5-beta,17-alpha-19-norpregn-20-yne-3-alpha,17-diol (2) in multigram quantities from estr-4-ene-3,17-dione is reported. Full characterization of these often-cited human metabolites of norethindrone is presented for the first time.
