Hydrolytic kinetic resolution of terminal mono- and bis-epoxides in the synthesis of insect pheromones: routes to (−)-( R )- and (+)-( S )-10-methyldodecyl acetate, (−)-( R )-10-methyl-2-tridecanone, (−)-( R )-( Z )-undec-6-en-2-ol (Nostrenol), (−)-(1 R ,7 R )-1,7-dimethylnonyl propanoate, (−)-(6 R ,12 R )-6,12-dimethylpentadecan-2-one, (−)-(2 S ,11 S )-2,11-diacetoxytridecane and (+)-(2 S ,12 S )-2,12-diacetoxytridecane

enantiomerically enriched epoxides and diols, which have been transformed into important insect sexpheromones. In this general approach, (−)-(R)- and (+)-(S)-10-methyldodecyl acetates from the smaller teatortrix moth were obtained, as was (−)-(R)-10-methyltridecan-2-one from the southerncornrootworm. The (S)-epoxide obtained from undec-1-en-6-yne was transformed to (−)-(R)-(Z)-undec-6-en-2-ol (Nostrenol)

The synthetic utility of the readily separated epoxides,
diols, epoxydiols and tetrols of high enantiomeric excesses, obtained by
hydrolytic kinetic resolution (HKR) of functionalised mono- and bisepoxides
with (salen)Co(OAc) complexes, is demonstrated by their efficient
transformations to important insect pheromones.
