  摘要：

  通过铑催化的加氢甲酰基化合成包含酒石酸衍生的单元和芳基单元的氮杂大环，随后以串联或逐步方式进行还原胺化。在荧光发射实验中，一些大环化合物显示出对过渡金属（例如锌或铑）的螯合亲和力。

  摘要：

  The reactive 2,3-O-isopropylidene-L-tartaryl chloride 4 was firstly synthesized from L-(+)-tartaric acid. Various chiral 2,3-O-isopropylidene-L-tartaramides 5 were prepared by aminolysis of the reactive L-tartaryl chloride 4 with primary and secondary amines.

• Carbonylation of functionalized diamine diols to cyclic ureas: application to derivatives of DMP 450
  作者：Ampofo K. Darko、F. Chris Curran、Chloé Copin、Lisa McElwee-White

  DOI：10.1016/j.tet.2011.04.015

  日期：2011.6

  inhibitor DMP 450 has been achieved via W(CO)6/I2-catalyzed carbonylation of diamine intermediates. Carbonylations of related functionalized diamines to derivatives of the DMP 450 core structure were also examined. Selected diamine diol substrates could be converted to the cyclic urea core structure by catalytic carbonylation without protection of the diol functionality.

• Synthesis of Chiral Aza Crown Ethers Having Exocyclic Hydroxy Groups and Their Use in Asymmetric Reduction of Ketones with Sodium Tetrahydridoborate

  New chiral diaza crown ethers with exocyclic hydroxy groups were synthesized by reactions of (2S,3S)-1,4-dibenzyloxy-2,3-bis(2-oxiranylmethoxy)butane with N,N'-dibenzyl-1,2-ethanediamine and (4S,5S)-4,5-bis(benzylaminomethyl)-2,2-dimethyl-1,3-dioxolane. Catalytic debenzylation of the products gave the corresponding derivatives having secondary amino groups. The obtained diaza crown ethers, as well as some known crown ethers, were used as asymmetric catalysts in the reduction of pinacolone and acetophenone with sodium tetrahydridoborate in methylene chloride. Depending on the catalyst structure, the optical yield of the reduction products ranged from 5 to 90%.
