Prediction of the absolute configuration of optically active methyl branched pheromones is possible by combining them with mesogens to give them liquid crystalline properties and measuring the helical senses of the chiral nematic phases.

Abstract According to our retrosynthesis, the main chain of the target molecule could be constructed using a C5 + C7 + C5 strategy. The key induction reaction afforded chiral methyl group moieties using different Evans templates with different configurations. Li 2 CuCl 4 was effectively employed in the Csp 3 Csp 3 coupling protocol. The target molecular was obtained in a 12.6% overall yield with nine
