Five new anellated 4H-1,4,2-diazaphospholes including the first examples of chiral 4H-1,4,2-diazaphospholes with the (−)-menthyl substituent have been prepared by two main routes: Hantzsch type cyclocondensation of 4-phenyl-2-amino-1,3-thiazole with chloromethyl dichlorophosphine and 4+1 cyclocondensation of cycloimmonium salts derived from 4-phenyl-2-amino-1,3-thiazole and 2-aminopyridine with PCl3
通过两个主要途径制备了五个新的带芳基的4 H -1,4,2-二氮杂磷,包括具有(-)-薄荷基取代基的手性4 H -1,4,2-二氮杂磷的第一个实例:Hantzsch型环缩合4-苯基-2-氨基-1,3-噻唑 和 氯甲基二氯膦 衍生自的环铵盐的4 + 1环缩合反应 4-苯基-2-氨基-1,3-噻唑 和 2-氨基吡啶使用PCl 3和NEt 3。新化合物已通过多核(1 H,13 C,31 P)NMR光谱进行了表征。5-苯并噻唑并[3,2- d ] [1,4,2]二氮磷腈2a的两个当量的受控水解水产生相应的两性离子次膦酸酯9,通过单晶X射线衍射阐明其结构。固态结构由牢固的N–H = O氢键控制,从而导致沿结晶a轴的链。这氯仿 分子通过较弱的C–H⋯O键和C–Cl⋯C卤素键整合在链中。
