Synthesis of 5,17-dihydroxy-5α, 17α, -19-norpregn-20-yn-3-one, a major photodegradation product of norethindrone
摘要:
A convenient synthesis of 5,17-dihydroxy-5 alpha,17 alpha-19-norpregn-20-yn-3-one in multigram quantities from norethindrone is reported. Confirmation of the structural assignment of this major photodegradation product of norethindrone is thus made.
