title: Stereoselective halogenation of the 16-hydroxymethyl-3-methoxy-13alpha-estra-1,3,5(10)-trien-17-ols and their solvolytic investigation.
abstract: The primary hydroxy functions of 16alpha-hydroxymethyl-3-methoxy-13alpha-estra-1,3,5(10)-trien-17beta-ol (3a) and 16beta-hydroxymethyl-3-methoxy-13alpha-estra-1,3,5(10)-trien-17alpha-ol (4a) were stereoselectively transformed into good leaving groups. On alkaline methanolysis of the 16-halomethyl or 16-tolylsulfonyloxymethyl derivatives, a new D-seco-13alpha-estrone derivative was obtained in high yield.
