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.

The reaction was quenched with aq Na2S2O3, and the aqueous layer was extracted with EtOAc (2 × 5 mL). The combined organic layers were washed with H2O and brine, dried (Na2SO4), and concentrated. The residue was purified by column chromatography [silica gel, PE–EtOAc (85:15)] to give a colorless oil; yield: 82.1 mg (83%).
