GLYCALS IN STEREOCHEMICAL SYNTHESIS SYNTHESIS OF (14R,8Z)-TROGODERMAL AND ITS (14S,8Z)-ENANTIOMER FROM DI-O-BENZOYL-D- AND -L-ARABINALS

Enantiomerically pure (14R)-14-methylhexadeca-8Z-enal (cis-trogodermal) - the aggregation pheromone of the khapra beetle (Trogoderma) - and its (14S,8Z)-enantiomer has been effected from di-O-benzoyl-D- and -L-arabinals.

A facile synthesis of (S)-trogodermal

A simple route for the synthesis of (S)-(Z)- and (S)-(E)-14-methyloctadec-8-en-1-al (Ia and Ib) has been developed.The achiral acetylene (9) is alkylated with the chiron bromide (S)-5 in the presence of BuLi as the base to give 10.This on subsequent functionalisation furnishes both Ia and Ib.
