  手性铱催化剂对异恶唑鎓三氟甲磺酸酯的不对称加氢

  摘要：

  在H 2存在下，铱催化剂[IrCl（cod）] 2-膦-I 2（cod = 1,5-环辛二烯）选择性地将三氟甲磺酸异恶唑鎓还原为异恶唑啉或异恶唑烷。当使用旋光性膦-恶唑啉配体时，铱催化的氢化反应以高至良好的对映选择性进行。将3-取代的5-芳基异恶唑鎓盐转化为4-异恶唑啉，对映体比例高达95：5（er）。手性顺式-异唑烷类化合物的最高获得时间为89:11，没有形成反式异构体，当底物在5位上具有伯烷基取代基时。机理研究表明，氢化铱（III）物种倾向于将其氢化物传递到异恶唑环的C5原子上。氢化物侵蚀导致3-异恶唑啉中间体形成手性异恶唑烷。同时，在4-异恶唑啉的选择性形成中，5-芳基取代基的空间位阻可能会阻碍C5原子处的氢化物攻击。

  Regioselective synthesis and side-chain metallation and elaboration of 3-aryl-5-alkylisoxazoles

  摘要：

  A number of 3-aryl-5-alkylisoxazoles have been synthesized in high yields by reacting arylnitrile oxides with free enolate ions regioselectively obtained by metallation of various alkyl methyl ketones with LDA in THF at -78degreesC followed by dehydration. Investigations concerning regioselective side-chain metallation and elaboration of one of them (3-phenyl-5-ethylisoxazole) have also been carried out. (C) 2002 Elsevier Science Ltd.

  dehydration. The two routes are not only both highly regioselective, but also complementary to each other as a pair of regioisomeric 3,5-disubstituted isoxazoles are readily prepared from one single ynone substrate. The efficiency of the two routes are further evaluated and demonstrated in the synthesis of three representative 3,5-disubstituted isoxazoles.

  报道了从炔酮向3，5-二取代异恶唑的两种区域选择性合成路线。一种途径是通过首先将炔酮转化为炔酮O-甲基肟，然后进行钯催化的分子内环化而发生的。另一个涉及通过炔酮和羟胺之间的环缩合形成5-羟基-4,5-二氢异恶唑，然后进行酸介导的脱水。这两种途径不仅具有高度的区域选择性，而且彼此互补，因为可以很容易地从一个单一的炔酮底物制备一对区域异构的3,5-二取代的异恶唑。进一步评估了这两种途径的效率，并在三种代表性的3,5-二取代的异恶唑的合成中得到了证明。
