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,先与强碱反应,然后再与磷酰化试剂(例如二环氨基膦卤化物或双-低烷基氨基膦卤化物)反应,生成通式为##STR2##的亚胺,其中R为二环氨基膦氧或双-低烷基氨基膦氧。R代表一个离去基团,在氮、氧、硫和碳含有亲核物质的情况下,会发生亲核置换,即亲核物质具有一个反应位点,是一个氮、氧、硫或碳原子,当环状亚胺发生亲核置换时,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。最终产物可用作制备药用有价值化合物的中间体,在某些情况下,它们本身也是有药用价值的化合物。
