  Applications of Organosulfur Chemistry to Organic Synthesis:  Total Synthesis of (+)-Himbeline and (+)-Himbacine

  摘要：

  Total syntheses of(+)-himbacine (1) and (+)-himbeline (2) are described. The synthesis involves the preparation of sulfone 38 and aldehyde 42 as single enantiomers followed by coupling of these compounds using a Julia-Lythgoe olefination. The preparation of sulfone 38 features an acid-promoted intramolecular Diels-Alder reaction of an alpha,beta-unsaturated thioester while the synthesis of 42 features a Beak, alkylation of piperidine 39.
