Abstract

A simple and efficient common route was developed for the syntheses of tetrahydrofuran-ring-containing natural products such as Hagen’s gland lactones and their epimers, a pheromone of the butterfly Idea leuconoe, an oxylipid, and some valuable synthons. Brown’s allylation, cross-metathesis, iodocyclization, and a tandem aminoxylation/allylation were employed as key steps in the syntheses.
