  Asymmetric Synthesis of Synargentolide A and Its 3-Epimer Using the RAMP-Hydrazone Methodology

  摘要：

  Synargentolide A was synthesized in 11 steps starting from the commercially available 2,2-dimethyl-1,3-dioxan-5-one, employing the SAMP/RAMP-methodology via an alpha,alpha'-bis-alkylation to generate the first two stereogenic centers with virtually complete asymmetric induction (de, ee > 99%). After the asymmetric synthesis of the triol fragment of the molecule, the delta-lactone moiety was constructed using an asymmetric allylation, esterification, and ring-closing metathesis sequence.
