- SYNTHESIS OF THE PROPIONATES OF (2R,8R)- AND (2RS,8R)-8-METHYL-2-DECANOL, THE ATTRACTANTS OF THE WESTERN CORN ROOTWORM
-
The propionate of (2R,8R)-8-methyl-2-decanol, (2R,8R)-1, an attractant of the western corn rootworm, Diabrotica virgifera Le Conte, has been prepared by a synthetic route in which enantiomerically pure methyl hydrogen (R)-3-methylglutarate, (R)-2, and (S)-glutamic acid, (S)-3, have been used as chiral precursors.In this convergent synthesis, (R)-2 and (S)-3 have been stereospecifically converted into (R)-1-bromo-3-methylpentane, (R)-4, and (R)-1,4-pentanediol, (R)-5, respectively.An analogous synthetic scheme has been followed to prepare biologically active (2RS, 8R)-1 starting from (R)-4 and racemic 5.
