methodology to obtain sec-dialkyl acetylenes based on the intramolecular hydride transfer from a secondary γ-benzyloxy group with well-defined absolute stereochemistry, ensured by a Sharpless asymmetric epoxidation reaction, to a cation generated by Lewis acid treatment of a tertiary Co2(CO)6-complexed propargylic alcohol.
