  A highly stereoselective synthesis of (E)-alkene dipeptide isosteres via organocyanocopper-Lewis acid mediation reaction

  摘要：

  A stereoselective synthesis of protected (E)-alkene dipeptide isosteres by the reaction of the mesylates of homochiral delta-aminated gamma-hydroxy (E)-alpha,beta-enoates with either RCu(CN)Li.BF3 or RCu(CN)MgX.BF3 reagent is described. The degree of diastereoselectivity has been found to be uniformly high except for the serine- and threonine-derived acetonides 77 and 81. The synthesis permits the introduction of sterically hindered appendages such as isopropyl and tert-butyl groups at the alpha position to the ester group. This methodology provides a new route to a wide range of modified (E)-alkene peptide mimics that may have biological importance.

  The “higher order” organozinc cuprates, R2Cu(CN)(ZnCl)2·2Mg(X)Cl·nLiCl, derived from admixture of LiCl (1∼2 equiv.), ZnCl2 (1 equiv.), RMgX (1 equiv.), and CuCN (0.5 equiv.) in a mixed solvent of THF and Et2O exhibit high diastereoselection of up to > 99: 1 in the synthesis of (E)-alkene dipeptide isosteres from γ-mesyloxy-α,β-unsaturated esters. Addition of lithium chloride is essential for the preparation

  “高阶”有机锌铜酸盐R 2 Cu（CN）（ZnCl）2 ·2Mg（X）Cl·nLiCl，由LiCl（1〜2当量），ZnCl 2（1当量），RMgX（ 1当量），而在THF和Et 2 O的混合溶剂中的CuCN（0.5当量）在从γ-甲磺酰氧基-α合成（E）-烯烃二肽等排体中表现出高达> 99：1的高非对映选择性， β-不饱和酯。添加氯化锂对于制备澄清的试剂溶液至关重要。
