Abstract
A short, simple and convenient chiron approach to (3R,4S,5R)-(-)-3,5-dihydroxy-4-decanolide, a hitherto unknown diastereomer of the reported structure of a naturally occurring acetogenin, (+)-polyporolide has been accomplished starting from a commercially available, inexpensive chiral pool molecule D-(+)-mannitol in nine efficient steps. An advanced intermediate synthesized from D-(+)-mannitol in six steps toward this end was further employed successfully to access two different natural products bearing two contiguous stereogenic centers. As a result, first chiron approach to formal total synthesis of an amide alkaloid, (4R,5R,2E)-4,5-dihydroxy-1-(piperidin-1-yl)dec-2-en-1-one and total synthesis of a male sex pheromone in parasitic Hymenoptera, (4R,5R)-(-)-5-hydroxy-4-decanolide have also been achieved.
