Abstract

1,164,834. Steroid compositions. SCHERING A.G. 26 Sept., 1966 [24 Sept., 1965], No. 42879/66. Headings A5B and A5E. ,[Also in Division C2] Compositions for use in human and veterinary medicine and as plant protection pesticides, comprise a compound 'of the formula: in which R, represents a hydrogen atom, an alkyl group or an acyl group and R 2 when the group 0R 2 is in the α- or #-configuration, represents a hydrogen atom, an alkyl group or an acyl group, or R 1 and R 2 together, when the group 0R 2 is in the #-configuration, represents an alkylene group, and R 3 represents hydrogen atom or an alkyl group and Y representing a hydrogen atom or an acyl or alkyl group, in admixture or conjunction with a suitable carrier. The products are highly effective as insect metamorphosis hormones and may be applied to crop areas for controlling pests.
