  Catalytic Enantioselective One-pot Aminoborylation of Aldehydes: A Strategy for Construction of Nonracemic α-Amino Boronates

  摘要：

  We report a strategy for the conversion of aldehydes to enantiomerically enriched alpha-amino boronates through the intermediacy of in situ-generated silylimines. This transformation is brought about by Pt-catalyzed asymmetric addition of B-2(pin)(2) across the imine double bond. An attractive feature of the intermediate diboration adduct is that it can be acylated directly and provides convenient access to important N-acyl alpha-amino boronic ester derivatives.

  含氧铵盐介导的醛类与腈的接触

  摘要：

  一种可扩展，高产，快速的途径，可通过乙氧基铵盐（4-乙酰氨基-2-2,2,6,6-四甲基哌啶-1-氟肟酸四氟硼酸）和六甲基二硅氮烷（HMDS）介导的醛类中的一系列腈的进入已经被开发出来。该反应可能涉及两个不同的化学转化：HMDS和醛之间可逆的甲硅烷基亚胺形成，然后由氧铵盐介导的氧化和甲硅烷基化反应制得腈。废氧化剂可以容易地回收并用于再生氧铵盐氧化剂。

  AbstractThis paper reports the synthesis of a series of N‐protected oxaziridines (N‐Moc, Boc, Z or Fmoc) and discusses their ability to deliver their N‐alkoxycar‐bonyl fragment to amines, enolates, sulfur, and phosphorus nucleophiles (electrophilic amination). These oxaziridines are prepared by oxidation of the corresponding imines with oxone or anhydrous MCPBA lithium salt as the source of oxygen. They transfer their N‐protected fragment to primary and secondary amines to give protected hydrazines in fair to excellent yield. The nitrogen transfer to free amino acids (in form of their R4N+ salts) is particularly fast, even at low temperature, providing L (or D) N‐protected α‐hydrazino acids. Enolates are C‐aminated to give N‐protected α‐amino ketones, esters, or amides in modest yield, due to a side aldol reaction of the unreacted enolate with the released benzaldehyde. With tertiary amines (Et3N), sulfides (PhSMe), and phosphines (Ph3P), amination and oxidation proceed in a parallel way; the amount of amination product increases when the temperature is lowered (kinetic control). Some of the factors that can orient the oxaziridine reactivity towards amination or oxidation of nucleophiles are considered.
