Process for production of derivatives of 1,3,2-oxazaphosphorinane of general formula 1, ##STR1## wherein R.sub.1 and R.sub.2 represent hydrogen atom or 2-halogenoalkyl group, and R.sub.1 and R.sub.2 are not at the same time hydrogen atoms, and X represents halogen atom is based, according to the invention, on the reduction of the respective 3-halogenoacyl derivatives of 1,3,2-oxazaphosphorinane of general formula 2, ##STR2## wherein the substituents have the above given meaning. The reduction is accomplished with the use of sodium borohydride in the presence of boron trifluoride etherate. Derivatives that are prepared by the procedure described here demonstrate antitumor activity.
一般式为1的1,3,2-氧杂磷环戊烷衍生物的生产过程,其中R1和R2代表氢原子或2-卤代烷基,且R1和R2不同时为氢原子,X代表卤原子,根据本发明,基于1,3,2-氧杂磷环戊烷的3-卤代酰基衍生物的还原,其一般式为2,其中取代基具有上述给定的含义。还原是在三氟化硼醚酸存在下使用硼氢化钠完成的。按照所述程序制备的衍生物表现出抗肿瘤活性。
