铜(I)配合物和碘[Cu(MeCN)4 ] PF 6 / I 2催化的β,γ-二氢转移反应的意外立体选择性合成(Z)-β-烯基取代的β-氨基膦酸酯
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
