Abstract

Procedure for solving a mixture of geometric isomers of derivatives of casÂșnico acid, in the seqcis and seqtrans isomers, of general formulas: ** (see formula) ** Where a means a radical (see formula) or o = o, and r means an alkyl radical containing from 1 to 4 carbon atoms or a phenyl or cyclohexyl radical, characterized in that a mixture of a compound of formula iia and its corresponding geometric isomer is subjected to formula iib to fractional crystallization and/or to chromatography.
