By a novel 'one pot' fragmentation-cyclization reaction 17β-hydroxy- 17α-substituted-16-oximino derivatives in the androstane and estrane series were converted to a new type of D-homo derivative.

The asymmetric unit of the title compound, 17α-benzyl-16-hydroxyimino-3-methoxyestra-1,3, 5(10)-trien-17β-ol, C26H31NO3, contains two molecules which differ in the orientations of the methoxy groups at C(3). The 17-hydroxy

By the action of acidic titanium trichloride upon 16-oximino-17α-benzyl-17α-hydroxy derivatives in the androstane and estrane series the 16-oxo-17-β-benzyl-17α-hydroxy derivatives 6 and 7 with inversed configuration at C17 were obtained. A mechanism for this novel rearrangement is proposed.
