    five-membered cyclic oxosulfonium ylide 3 with β-acetoxy-α-methylene ketones in the presence of two equimolar amounts of base afforded the cycloheptene oxide derivatives 7a−i as single stereoisomers in 19−77% yields. The products were considered to form through a Michael-type addition of the ylide, followed by elimination of the acetoxy group and an intramolecular Corey−Chaykovsky reaction. On the

    日期:2015.12.18
    (±)-Tetrabenazine was synthesized in six steps from commercially available compounds. The key cyclization substrate was assembled rapidly via Baylis–Hillman and aza-Michael reactions. Annulation of the final ring was achieved through visible light photocatalysis, wherein carbon–carbon bond formation was driven by the oxidation of a tertiary amine. Solvent played a critical role in the photoredox cyclization
