  二磺酰亚胺催化的N-烷基亚胺的不对称还原

  摘要：

  在Boc 2 O存在的情况下，已开发出一种以Hantzsch酯为氢源的手性二磺酰亚胺（DSI）催化N烷基亚胺的不对称还原。该反应可提供具有出色收率和对映选择性的Boc保护的N-烷基胺。该方法可耐受多种烷基胺，从而说明了酮与各种胺的一般还原性交叉偶联的潜力，并已用于药物（S）-利伐斯的明，NPS R-568盐酸盐的合成，以及（R）-芬迪林。

  ine and THF soluble CuCN·2LiCl react with vinyl iodides, vinyl triflates, β-iodo-α,β-enoates, propargyl mesylates, and allyl bromide to afford the substitution products with excellent enantioselectivity. Excellent enantiomeric ratios are obtained in the conjugate addition reactions with methyl vinyl ketone while low enantiomeric ratios can be achieved with acrylate esters using HMPA/TMSCl activation

  AbstractThe palladium‐catalyzed ligand‐controlled arylation of α‐zincated acyclic amines, obtained by directed α‐lithiation and transmetalation, is described. Whereas PtBu3 gave rise to α‐arylated Boc‐protected amines, more flexible N‐phenylazole‐based phosphine ligands induced major β‐arylation through migrative cross‐coupling.
• Formation of benzylamines from triazene compounds via a 1,2-proton shift

  A new approach to benzylamines using triazene compounds has been developed that is facilitated by the lithiation of aryltriazenes followed by treatment with an electrophile. The regioselectivity of the reaction can be controlled by means of the substituents in the aryl group. The reaction contains the following steps: intramolecular carbon-carbon bond formation involving lithiation of an alkyl group on a 3-nitrogen atom; a 1,2-proton shift; and the subsequent release of nitrogen gas. Through the use of a deuterated triazene, we were able to determine that the reaction proceeds through a 1,2-proton shift. (c) 2006 Elsevier Ltd. All rights reserved.

  A chiral disulfonimide (DSI)‐catalyzed asymmetric reduction of N‐alkyl imines with Hantzsch esters as a hydrogen source in the presence of Boc2O has been developed. The reaction delivers Boc‐protected N‐alkyl amines with excellent yields and enantioselectivity. The method tolerates a large variety of alkyl amines, thus illustrating potential for a general reductive cross‐coupling of ketones with diverse
