• Enantioselective Synthesis of α-Alkyl,α-Vinyl Amino Acids via [2,3]-Sigmatropic Rearrangement of Selenimides
  作者：Alan Armstrong、Daniel P. G. Emmerson

  DOI：10.1021/ol1030926

  日期：2011.3.4

  Chiral α-alkyl,α-vinyl amino acids (quaternary vinyl glycine derivatives) are prepared with high levels of enantiomeric purity by [2,3]-sigmatropic rearrangement of allylic selenimides. The required trisubstituted allylic selenides are prepared by an organocatalytic α-selenenylation of aldehydes followed by Horner−Wadsworth−Emmons (HWE) olefination. Both (E)-and (Z)-geometrical isomers are available

This relatively stable compound was utilized for an efficient α-selenenylation reaction of aldehydes and ketones catalyzed by l -prolinamide under mild reaction conditions. The organocatalytic asymmetric α-selenenylation of an aldehyde was also studied and the reaction was found to proceed with high enantioselectivity (96% ee).

  elimination/hydrolysis of these mixtures afforded alpha,beta-unsaturated aldehydes in 50-80% overall yields. In the case of tertiary alpha-bromoacetals, treatment with benzeneselenolate afforded only dehydrobromination products as mixtures of isomers. The presence of at least a catalytic amount of the organoselenium reagent was found to be crucial for olefin formation. A SET-mechanism, involving benzeneselenolate-induced

  研究了乙酰化，α-溴化，亲核性苯硒基化，氧化消除/水解作为醛类α，β-脱氢的新方法。用溴在二氯甲烷中的乙缩醛处理得到相应的α-溴缩醛，产率为80-90％。然后，通过用由二苯基二硒化物，肼和碳酸钾在二甲基亚砜中原位生成的苯硒酸酯处理，可以方便地实现亲核性苯基硒烯基化。无支链的α-溴缩醛可干净地提供取代产物，而β和γ支链的则通过形式上的溴化氢损失而产生大量的α，β-不饱和缩醛。这些混合物的氧化消除/水解以50-80％的总产率提供α，β-不饱和醛。在叔α-溴缩醛的情况下，用苯硒烯酸酯处理仅得到作为异构体混合物的脱氢溴化产物。发现至少催化量的有机硒试剂的存在对于烯烃形成至关重要。提出了一种SET机制，包括苯硒酸酯诱导的电子转移到卤化物，溴离子的损失以及氢原子或质子/电子，用于苯甲酸酯促进的消除反应。旨在在分子内环化或开环反应中捕获以碳为中心的自由基的实验未能提供任何自由基中间体的证据。发现至少催化
