  Dimethylzinc-Mediated Additions of Alkenylzirconocenes to Aldimines. New Methodologies for Allylic Amine and C-Cyclopropylalkylamine Syntheses

  摘要：

  Hydrozirconation of alkynes with zirconocene hydrochloride followed by in situ transmetalation to dimethylzinc provides access to reactive alkenyl organometallic reagents from readily available precursors. Upon addition of imines, 1,2-attack leads to synthetically useful allylic amine building blocks. In the presence of CH2I2 or CH2Cl2, the N-metalated allylic amide intermediate is cyclopropanated and C-cyclopropylalkylamines are formed in high yield and excellent diastereoselectivities favoring the anti products. The use of enynes as starting materials for this domino reaction provides conjugated biscyclopropanes and thus allows the stereoselective formation of five new carbon-carbon bonds. A transition state that explains the need for both zirconocene complex and alkyl zinc in the cyclopropanation reaction is proposed.

• The Supersilyl Group as a Carboxylic Acid Protecting Group: Application to Highly Stereoselective Aldol and Mannich Reactions
  作者：Jiajing Tan、Matsujiro Akakura、Hisashi Yamamoto

  DOI：10.1002/anie.201300102

  日期：2013.7.8

  Silyl superpowers: The supersilyl group was investigated as a superior carboxylic acid protecting group. Supersilyl esters were also utilized as stable carboxylic acid synthetic equivalents in highly stereoselective aldol and Mannich reactions (see scheme). The value of this method lies in easy photodeprotection and in the rapid synthesis of polyketide subunits.

  organoboron reagents with imines and carbonyls; the products of the reactions are enantiomerically pure amines and alcohols, which might serve as intermediates in the preparation of biologically active molecules. A distinguishing feature of this catalyst class is the presence of a ‘key’ proton embedded within their structure. Catalysts are derived from the abundant amino acid valine and are prepared in

  可用于通过对映选择性转化合成复杂有机化合物的催化剂的发现是生命科学进步的核心。出于这个原因，许多化学家的目标是发现可以制备手性分子主要作为一种镜像异构体的催化剂。理想的催化剂不应含有贵重元素，并且应通过操作简单的程序在几小时内完成反应。这里我们介绍了一组可以催化不饱和有机硼试剂与亚胺和羰基反应的有机小分子；反应的产物是对映异构纯的胺和醇，它们可以作为制备生物活性分子的中间体。这种催化剂类别的一个显着特征是存在嵌入其结构中的“关键”质子。催化剂来源于丰富的氨基酸缬氨酸，使用廉价的试剂分四步大量制备。反应是可扩展的，不需要严格的条件，并且可以在室温下用低至 0.25 摩尔% 的催化剂在不到 6 小时内进行，以产生超过 85% 的产率和≥97:3 的对映体比率的产物。转化的效率、选择性和操作简单性以及硼基试剂的范围有望使这一进步对胺和醇合成的未来进展具有重要意义，这些在化学、生物学和医学中是有用

  A zinc-mediated Mannich-type transformation of 2,2,2-trifluorodiazoethane with a series of imines has been described. This method provides facile access to a wide range of trifluorodiazoethyl-substituted amines in moderate to high yields under mild conditions. The synthetic utility of the afforded adducts is demonstrated by further transformations to valuable β-CF3-amines.

  作者：Peter Wipf、Corey R. J. Stephenson、Kazuo Okumura

  DOI：10.1021/ja038623a

  日期：2003.12.1

  The organometallic multicomponent reaction of alkenyl zirconocene, alkynyl imine, and zinc carbenoid in the presence of dimethylzinc leads to novel C,C-dicyclopropylmethylamines. The formation of intermediate bicyclo[1.1.0]butanes represents the first synthetically useful example of a double C,C-sigma-bond insertion, and the increase in structural complexity from starting materials is highlighted by the formation of nine new C,C-bonds in the final product.
