  Enantioselective synthesis of non-proteinogenic 2-arylallyl-α-amino acids via Pd/In catalytic cascades

  摘要：

  An efficient synthesis of both R- and S-enantiomers of 2-arylallyl-alpha-amino acids via a diastereoselective Pd/In mediated catalytic allylation of chiral N-sulfinyl-alpha-imino esters is described. The potential for further enhancement of molecular complexity and creating contiguous chiral centres by interfacing these processes with catalytic cyclisation-anion capture methodology is demonstrated.

  DOI：10.1039/b700433h

  日期：——

  A general route to ruthenium pyridocarbazole half-sandwich complexes is presented and applied to the synthesis of sixteen new compounds, many of which have modulated protein kinase inhibition properties. For example, the incorporation of a fluorine into the pyridine moiety increases the binding affinity for glycogen synthase kinase 3 by almost one order of magnitude. These data are supplemented with cyclic voltammetry experiments and a protein co-crystallographic study.

  提出了合成钌吡啶卡巴唑半夹心配合物的一般路线，并应用于合成十六种新化合物，其中许多化合物具有调节蛋白激酶抑制特性的性能。例如，在吡啶部分引入氟原子可使对糖原合酶激酶3的结合亲和力增加近一个数量级。这些数据显示补充了循环伏安实验和蛋白质共结晶学研究。
