  区域专一和β-氨基（高度立体选择性合成Ž）-enylphosphonates经由通过的AgOTf催化二烷基α-diazophosphonates的β氢迁移反应†

  摘要：

  为了研究金属卡宾在1,2-迁移反应中的空间效应，已经从天然氨基酸制备了一系列带有不同取代基的二烷基α-重氮膦酸酯。使用AgOTf / NaBAr F络合物对重氮膦酸酯进行重氮分解，导致β氢迁移，从而以高收率和高区域选择性和立体选择性得到β-氨基（Z）-烯基膦酸酯。一种可能的反应机理表明，空间效应会极大地影响几何异构性。这种构造（Z）-β-氨基乙烯基膦酸酯的新方法应该在有机合成中具有普遍的用途。

  The copper-catalyzed C–H functionalization/O–H insertion reaction of α-diazophosphonates with alcohols has been developed with iodine as an additive. In order to understand this reaction, we present here a possible mechanism for the combined reaction. This process provides straightforward access to tertiary β-alkoxy substituted β-aminophosphonate derivatives with moderate to good yields.

  insertion reactions of α-diazophosphonates with indole or pyrrole derivatives catalyzed by trifluoroborane have been developed. The reaction protocol was effective for regioselective C–H insertion depending on the substitution pattern on the indole moiety and carbene migratory model. This represents the first straightforward access to N-unsubstituted β-(3-indol)-β-aminophosphonates and β-(2-pyrrol)-β-aminophosphonates

  日期：——

  The regiospecific and stereoselective 1,2-migration reaction of dialkyl alpha-diazophosphonates for the synthesis of beta-amino (E)-enylphosphonates is developed utilizing tetrakis(acetonitrile)copper(I) hexafluorophosphate [Cu(MeCN)(4)PF6] as the catalyst and N,N-dimethylformamide as an additive. A possible mechanism for the 1,2-migration reaction involving a metal carbene is presented. An investigation on the E/Z isomer selectivity of this process demonstrates that steric factors play an important role on the outcome. This process provides a straightforward access to beta-amino (E)-enylphosphonates in moderate to good yields.

  AbstractA series of dialkyl α‐diazophosphonates has been prepared from natural amino acids. The diazo decomposition of these diazophosphonate compounds with tetrakis(acetonitrile)copper(I) hexafluorophosphate/iodine, [Cu(MeCN)4]PF6/I2, as catalyst has been investigated. It was found that the diazo decomposition of dialkyl α‐diazophosphonates gave a mixture of β,γ‐dihydrogen shift and 1,2‐hydride migration products and afforded β‐alkenyl‐substituted β‐amino phosphonates with the Z configuration. The mechanism of this novel diazo decomposition process was discussed.magnified image
