  Resolvin E1的全合成

  摘要：

  Resolvin E1（RvE1）是解决炎症的内源性介质，它是通过C15–C20醛与具有乙烯基碘部分的C10–C14 nium盐之间的Wittig反应合成，然后将生成的碘代乙烯基碘与Suzuki-Miyaura偶联的C1-C9部分的乙烯基硼烷，是通过硼氢化从相应的乙炔衍生而来的。这些部分的C5和C18手性中心是由外消旋的γ-TMS烯丙基醇通过不对称环氧化反应动力学拆分而形成的，而C10–C14的手性中心是由相应的γ-TMS的不对称氢转移反应构建的乙炔酮。

  Catalytic Asymmetric Addition of Polyfunctional Dialkylzincs to .beta.-Stannylated and .beta.-Silylated Unsaturated Aldehydes

  摘要：

  The addition of functionalized dialkylzincs to readily available beta-stannylated or beta-silylated unsaturated aldehydes in the presence of a catalytic amount of (1R,2R)-1,2-bis(trifluorosulfonamido)cyclohexane (8 mol%) provides chiral allylic alcohols in good yields (60-90%) and excellent enantioselectivity (usually in the range of 85-95% ee). The synthetic utility of these allylic alcohols as chiral building blacks is demonstrated. The gamma-stannylated allylic alcohols were submitted to a Stille coupling leading to polyfunctional allylic alcohols and gamma-alkoxy enones. A treatment with CuCN in N-methylpyrrolidone at 130 degrees C provided chiral unsaturated gamma-hydroxy nitriles. Finally, the desilylation of the gamma-silylated alcohols gave chiral allylic alcohols having a terminal double bond. The catalytic asymmetric addition was found to show an important inverse temperature dependance. A mechanism for this addition is proposed.

  Factors that govern chemical and optical yields of methyl gamma-hydroxy-alpha,beta-unsaturated esters 1 formed in reactions of optically active sulfinylacetates 2 with aldehydes (the ''SPAC'' reaction) are defined. Racemic samples of these chirons (1) can be resolved via acylations mediated by crude preparations of the lipase Pseudomonas K-10 in organic solvents. Combinations of asymmetric SPAC reactions with these biocatalytic resolutions provide routes to highly optically active esters 1 in good yields. This methodology is applied in a completely asymmetric synthesis of (4S-cis)-5-(cyclohexylmethyl)-4-hydroxy-2-pyrrolidinone (15), a cyclic derivative of (3S,4S)-4-amino-5-cyclohexyl-3-hydroxypentanoic acid (ACHPA).
