ChemInform Abstract
Acylketene acetals such as (I) undergo facile organolithium addition (. fwdarw. (III)) and conjugate hydroboration reaction (→ (IV)). The enantiomerically pure acylketene acetal (VI) is employed in the synthesis of the stereoisomers (XII)-(XV) of the Mtpa-ester of the insect pheromone sitophilure (XV).
