  Lewis Acid-Mediated Highly Regioselective S_N2-Type Ring-Opening of 2-Aryl-N-tosylazetidines and Aziridines by Alcohols

  摘要：

  Lewis acid-mediated highly regioselective S(N)2-type ring-opening of 2-aryl-N-tosylazetidines with alcohols to afford various 1,3-amino ethers in excellent yields with good enantiomeric excess is described. Similar S(N)2-type ring-opening of chiral 2-phenyl-N-tosylaziridine with various alcohols produces the corresponding nonracemic 1,2-amino ethers in excellent yields and good ee. The mechanism of the ring-opening of aziridines and azetidines via an S(N)2 pathway is supported by the formation of nonracemic amino ethers.

  We have developed a palladium-catalyzed regioselective and enantiospecific ring-opening Suzuki–Miyaura arylative cross-coupling of N-tosyl-2-arylazetidines to give enantioenriched 3,3-diarylpropylamines. This reaction represents an example of transition-metal-catalyzed ring-opening cross-coupling using azetidines as a non-classical alkyl electrophile. Density functional theory rationalized the mechanism

  我们开发了一种钯催化的区域选择性和对映特异性开环 Suzuki-Miyaura 芳基化交叉偶联的N-甲苯磺酰基-2-芳基氮杂环丁烷，得到对映体富集的 3,3-二芳基丙胺。该反应代表了使用氮杂环丁烷作为非经典烷基亲电子试剂的过渡金属催化开环交叉偶联的一个例子。密度泛函理论使完整催化循环的机制合理化，包括决定选择性的氮杂环丁烷开环、与水反应、决定速率的金属转移和还原消除。通过多组分人工力诱导反应（MC-AFIR）方法系统地确定了选择性决定开环步骤的过渡态，以解释反应的区域选择性。

  yield and enantioselectivity of a variety of substituted nonracemic morpholines and their homologues is described. The reaction proceeds via an SN2-type ring opening of activated aziridines and azetidines by suitable halogenated alcohols in the presence of Lewis acid followed by base-mediated intramolecular ring closure of the resulting haloalkoxy amine.

  Lewis acid catalyzed quaternary ammonium salt mediated highly regioselective ring-opening of chiral activated aziridines and azetidines with alcohols to nonracemic β- and γ-amino ethers has been developed. The reaction mainly proceeds via an SN2 pathway, and the partial racemization of the starting substrate was effectively controlled by using quaternary ammonium salts. β- and γ-amino ethers are obtained
