Proceeding from the readily available methyl (5S)-5-hydroxy-3-methylidenehexanoate obtained by the reaction of asymmetric allylation a new approach has been developed to the preparation of (6S)-6-undecyl-5,6-dihydro-2H-pyran-2-one which has underlain the synthesis of (6S)-6-undecyltetrahydro-2H-pyran-2-one, the pheromone of oriental hornet VespaOrientalis, and also the formal synthesis of the tetrahydrolipstatin

Simple and efficient asymmetric synthesis was developed of the cyclic scaffold of (-)-valilactone, an effective inhibitor of the pancreas lipase, applying the Keck allylation in the key stage of building up the carbon skeleton of the target molecule and of the unnatural (S)-isomer of Massoia lactone, lachnelluloic acid, possessing fungicidal properties, and (5R,7S)-7-hydroxy-5-dodecanolid, pheromone

Abstract New isoxazoline derivatives have been synthesized in high yields by cycloaddition of acetonitrile oxide to α,β-unsaturated β-methyl-δ-lactones. These unsaturated lactones have been used to obtain β-methyl branched saturated lactones and lactams, as well as lactones with an inversed configuration of hydroxy group, following the divergent approach.
Total synthesis of (-)-valilactone, an efficient pancreatic lipase inhibitor, was accomplished with the use of Keck allylation in the key step of construction of the target carbon skeleton.
