ABSTRACT:
Serricornin, the attractant pheromone of the cigarette beetle, is synthesized in high enantiomeric and diastereomeric purity via a series of reactions of asymmetric 2-(1-haloalkyl)-1,3,2-dioxaborolanes with Grignard reagents, which lead to the key intermediate the carbon-carbon double bond of and sodium periodate yields serricornin.
