Summary:1288437 Polyene compounds F HOFFMANN-LA ROCHE & CO AG 30 June 1970 [4 July 1969] 51560/71 Divided out of 1288435 Heading C2C The invention comprises compounds of the formula wherein R is C 1-5 alkyl or haloalkyl, aryl or aryl which is mono- or di-substituted by C 1-5 alkyl, halogen or NO 2 . They may be obtained by oxidizing a compound of formula with an oxidizing agent such as MnO 2 , GO 3 or SO 3 . Examples are given for the production of the compounds. The compounds of Formula VI may be obtained by treating an epoxide of formula with SeO 2 , the epoxide of Formula V may itself be otbained by treating a compound of formula with an organic peroxide, the compound of Formula IV may itself be obtained by reacting a compound of the formula via a Wittig reaction with a compound of formula wherein Y(-) is a halide anion.
