Abstract

1438479 Ketals; steroid oximes ALLIED CHEMICAL CORP 11 March 1975 [15 April 1974] 10159/75 Headings C2C and C2U The invention comprises compounds of the formula where R1 is H, C 1 -C 4 alkyl or phenyl, or R1 together with the 6-membered ring forms a polycyclic structure, X is a group of the formula where R2 and R3 are C 1 -C 10 alkyl, cyclohexyl or cyclohexyl substituted by C 1 -C 4 alkyl and R4 and R5 are H or C 1 -C 10 alkyl or R4 and R5 together with Ca and Cb form a cyclohexyl group. The invention further comprises dimers of the formula where X is a group of Formula II and R1, R2 and R3 are as defined above. Compounds of Formula IV may be prepared by reacting compounds of the formulµ and R3ONO in an inert solvent. Compounds of Formula I may be prepared by isomerizing compounds of Formula II or by reacting a compound of Formula V with a nitroxyl halide, a base and an alcohol of the formula R3OH in an inert solvent, or by reacting an R1 substituted cyclohexanone with a nitroxyl halide, an acid and a diol of the formula in the presence of an inert solvent having a dielectric constant of at least 12 and subsequently neutralizing the resulting acid salt intermediate. Compounds prepared include 3,3-dimethoxy- 2-oximocholestane.
