Compounds of the general formula ##STR1## are reacted with a strong base followed by a phosphorylating agent, such as dicyclicaminophosphinic halide or bis-di-lower alkylaminophosphinic halide to produce an imine of the formula ##STR2## wherein R is dicyclicaminophosphinyloxy or bis-di-lower alkylaminophosphinyloxy. R represents a leaving group which will undergo nucleophilic displacement with nitrogen, oxygen, sulfur and carbon containing nucleophiles, that is, nucleophiles which have, as a reactive site, a nitrogen, oxygen, sulfur or carbon atom, such that, when the cyclic imine undergoes nucleophilic displacement, there is formed C--N, C--O, C--S and C--C bonds between the carbon atom of the cyclic imine and the nucleophilic group. The end products may be utilized as intermediates in the production of pharmaceutically valuable compounds and, in some instances, are pharmaceutically valuable compounds per se.
通式为##STR1##的化合物与强碱反应,然后与磷酰化剂(例如二环胺磷酸卤化物或双二烷基胺磷酸卤化物)反应,生成通式为##STR2##的亚胺,其中R为二环胺磷氧基或双二烷基胺磷氧基。R代表一个离去基团,将与含氮、氧、硫和碳的亲核试剂发生亲核取代反应,即具有氮、氧、硫或碳原子作为活性位点的亲核试剂,使得当环状亚胺发生亲核取代时,在环状亚胺的碳原子和亲核基团之间形成C-N、C-O、C-S和C-C键。最终产物可用作制药有价值化合物的中间体,并且在某些情况下本身就是有价值的药用化合物。
