摘要: The paper describes an asymmetric approach to the synthesis of (2S,4S,6S)-2,4,6-trimethylnonyl segment siphonarienes. key step used is a newly developed methodology obtain sec-dialkyl acetylenes based on theintramolecular hydride transfer from secondary γ-benzyloxy group with well-defined absolute stereochemistry, ensured by Sharpless epoxidation reaction, cation generated Lewis acid treatment tertiary Co 2 (CO) 6 -complexed propargylic alcohol.
