  Stereoselective Alkylation of (S)-N-Acyl-4-isopropyl-1,3-thiazolidine-2-thiones Catalyzed by (Me₃P)₂NiCl₂

  摘要：

  The structurally simple (Me3P)(2)NiCl2 complex catalyzes S(N)1-type alkylations of chiral N-acyl thiazolidinethiones with diarylmethyl methyl ethers and other stable carbenium cations. The former can contain a variety of functional groups and heteroatoms at the alpha-position. The resultant adducts are isolated as single diastereomers in high yields and can be converted into enantiomerically pure derivatives in a straightforward manner.

  日期：2016.6.17

  A concise synthesis of the C9–C19 fragment of peloruside A that is both highly stereoselective and efficient is described. Achieving an overall yield of 23% over 14 steps, this synthesis not only is high yielding but also involves four chromatography steps. This approach is based on the addition of metal enolates of chiral auxiliary scaffolds generated by either catalytic or stoichiometric amounts

  nickel-catalyzed alkylation of chiral N-acyl-4-isopropyl-1,3-thiazolidine-2-thiones using a commercially available nickel(II) complex, (Me3P)2NiCl2, has been developed for tropylium and trityl tetrafluoroborate salts. The reaction provides a single diastereomer of the corresponding adducts in good to high yields, which, in turn, can be easily converted into a wide array of enantiomerically pure compounds that

  [structure: see text]. A convergent and module-based strategy for the asymmetric synthesis of the western hemisphere (C1-C17 fragment) of salinomycin has been devised. This new synthetic approach relies on highly stereoselective C-glycosidation and aldol processes.
