  1,2-Hydride Migration in Dialkyl α-Diazophosphonates Catalyzed by [Cu(MeCN)4]PF6: A Novel Approach to β-Amino (E)-Enylphosphonates

  摘要：

  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.

  摘要：

  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

  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

  to give β-amino (Z)-enylphosphonates in good yields with high regio- and stereoselectivity. A possible reaction mechanism shows that the steric effect could dramatically influence the geometric isomerism aptitude. This new method for constructing (Z)-β-amino vinylphosphonates should be of general utility in organic synthesis.
