  Epimerization of trans-3-Arylaziridine-2-carboxylates at the C3 Position

  摘要：

  We describe here effective epimerization of trans to cis isomer of 1-benzyl-3-arylaziridine-2-carboxylates. The combination of samarium metal, iodine and N,N-dimethylaminoethanol promoted the epimerization of trans isomer to a ca. 1 : 1 mixture of cis and trans ones. Investigating more effective catalyst, indium chloride was found to afford a ca. 2 : 1 mixture of cis and trans isomers. Epimerization at benzylic position in the aziridines is suggested from the result with optically active ones. Preparation of cis-2-indolylaziridine towards construction of aziridinomitosene skeleton was achieved in this epimerization reaction.

• Selective Construction of C−C and C=C Bonds by Manganese Catalyzed Coupling of Alcohols with Phosphorus Ylides

  manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon‐carbon single (C−C) and carbon‐carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C−C vs. C=C bonds can be controlled by the

  在本文中，我们报道了锰与磷酰化物的锰催化偶联。伯醇与磷酰化物偶联形成碳碳单键（CC）和碳碳双键（C = C）的选择性可以通过配体控制。在更具挑战性的仲醇与磷酰化物的转化中，通过反应条件，即碱的量，可以控制形成CC与C = C键的选择性。偶联反应的范围和局限性通过21种醇和15种烷基化物的转化得到了彻底评估。值得注意的是，与基于贵金属络合物作为催化剂的现有方法相比，本催化体系基于富含稀土的锰催化剂。该反应也可以在顺序的一锅法反应中进行，该反应在锰催化的C-C和C = C键形成后就地生成磷叶立德。机理研究表明，CC键是通过借位氢途径生成的，而C = C键的形成遵循无受体的脱氢偶联途径。

  A simple catalyst of Ni(OAc)2 and P(t-Bu)3 enables selective C-alkylation of thioacetamides and primary acetamide with alcohols for the first time. Monoalkylation of thioamides, amides and t-butyl esters occurs in excellent yields (>95%). Mechanistic studies reveal that the reaction proceeds via a hydrogen autotransfer pathway.

  Catalytic α‐alkylation of esters with primary alcohols is a desirable process because it uses low‐toxicity agents and generates water as the by‐product. Reported herein is a NCP pincer/Ir catalyst which is highly efficient for α‐alkylation of a broad scope of unactivated esters under mild reaction conditions. For the first time, alcohols alkylate unactivated α‐substituted acyclic esters, lactones,

  酯与伯醇的催化α-烷基化是一个理想的过程，因为它使用低毒性的试剂并产生水作为副产物。本文报道的是一种NCP夹钳/ Ir催化剂，在温和的反应条件下，该催化剂对各种未活化酯的α-烷基化反应非常有效。醇类首次将未活化的α-取代的无环酯，内酯甚至甲基和乙酸乙酯烷基化。该方法可用于具有不同结构和官能团的羧酸衍生物的合成，其中某些是不可能通过常规的用烷基卤化物进行烯醇化烷基化而获得的。
