Me. Martin et al., SELECTIVE ENZYMATIC-HYDROLYSIS OF (Z,E)-DIMETHYL-2,4-HEXADIENEDIOATE - PREPARATION OF (Z,E)-DIFUNCTIONALIZED DIENES, Tetrahedron, 51(17), 1995, pp. 4985-4990
Enzymatic hydrolysis of (Z,E)-dimethyl-2,4-hexadienedioate 6 by Pig Li
ver Esterase mainly led to (2E,4Z)-5-methoxycarbonyl-2,4-pentadienoic
acid 2a. This compound was a starting material for the preparation of
other difunctionalized dienes.
