Abstract
PURPOSE: To prepare optically-active title compound, which is a sex pheromone of pine sawflies or its intermediate, easily by reacting optically active 2,3-epoxybutane and an alkyl metal compound.
CONSTITUTION: Optically-active erythro-3-methylalkan-2-ol of formula III is prepared by reacting optically active 2, 3-epoxybutane of formula I and an alkyl methal compound of formula II (R1 is alkyl; R2 is alkyl, arylthio, alkoxy, etc.). The reaction is carried out in an inert solvent at, -70W50°C, preferably -50W20°C. For example, erythro-(2R,3R,7S)-(+)-3,7-dimethylpentadecan-2-ol is obtained.
