A stereospecific synthesis of optically pure (-)-α-multistriatin

An efficient stereo- and enantiospecific synthesis of (-) -α-multistriatin from (L)- malic acid is described. The key steps of this synthesis are the stereoselective alkylation of the hydroxylactone 5 and the acid equilibration of the esters 9 and 10.

A NEW SYNTHESIS OF (-)-Α-MULTISTRIATIN, THE PHEROMONE OF THE SMALLER EUROPEAN ELM BARK BEETLE

(-)-Α-Multistriatinoctane> was synthesized from (Z)-2-butene-1,4-diol monobenzyl ether by employing the sharpless asymmetric epoxidation and the regioselective epoxide cleavage with Me3Al as the k
