Some new 17a-homolactones were prepared from 3β-hydroxy-16- (hydroxyimino)androst-5-en-17-one (1) as a starting compound, which was transformed first to the corresponding 17α-phenyl and 17α-benzyl derivatives 2 and 3. The structure of compound 3 was confi

D-Homo derivatives in the androstane and estrane series, 12-19, were synthesized by a fragmentation-cyclization reaction of 16-oximino-17-hydroxy-17-substituted derivatives 3-9, or by cyclization of the corresponding D-seco derivatives 20-26. The structur

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.
