In order to check the corresponding compound at 31P NMR –45.4 ppm, stable pentacoordinate spirobicyclic 2-phenoxy-1,3-phenylene-dioxo-1,3,2-iminoacetoxyphosphoranes were synthesized through a new and efficient method whereby phosphorus pentachloride was displaced stepwise by catechol, N,O-bisamino acid and phenol, or catechol, phenol and N,O-bisamino acid, their 31P NMR chemical shifts are at about 31P NMR –45.0 ppm, the results showed that the compound 4 at 31P NMR –45.4 ppm was pentacoordinate phosphorane containing amino acid residue.
采用磷谱跟踪来研究上述成肽反应机理。例如在氮气保护下,0.1mmol O,O-亚苯基磷酰氯(1)和0.15mmol N,O-二苯丙氨酸(2)苯溶液加入0.6ml核磁管中,混合均匀,反应过程用磷谱检测。反应1分钟后,起始原料1(δp=19ppm)很快转变成N-磷酰苯丙氨酸的三甲基硅基酯(3)(δp=19.8ppm),在8分钟内,3完全转变成苯丙氨酸磷烷4(δp =-45.4ppm),同时出现环磷三酯(6)(δp=3.5ppm)。随着反应的进行,对应于化合物4的峰逐渐变小,而6逐渐变大。
