An expedient preparation of chiral building blocks having levoglucosenone chromophore: a new enanticontrolled route to (–)-β-multistriatin and (+)-exo-brevicomin

Abstract

2-Alkenylfurans are transformed enantioselectively into the bicyclic enones having the levoglucosenone chromophore, whose synthetic utility is demonstrated by a stereocontrolled synthesis of two insect pheromones (–)-β-multistriatin and (+)-exo-brevicomin.
