Abstract

Procedure for the preparation of new crocetínicos esters of the formula ** (See formula) ** in which R4 and R5 are alkyl containing in each case from 10 to 14 carbon atoms, characterized by the condensation of 4,9-dimethyl-dodeca-2,4,6,8,10-pentaen-1,12-dial with a phosphorane of the general formula ** (See formula) ** wherein R3 is alkyl of 10 to 14 carbon atoms and A is a phenyl radical, optionally provided with lower alkyl or lower alkoxy groups, in an inert solvent and then cleaved triphenylphosphine oxide.
