Abstract
A 1-step synthesis of 4-hydroperoxyifosfamide and 4-hydroperoxytrofosfamide is described. The method involves direct ozonation of ifosfamide and trofosfamide and offers improved yields in comparison with Fenton oxidation and greater convenience in comparison with ozonation of the appropriate 3-butenyl phosphorodiamidate. Evaluation of the 4-hydroperoxy derivatives of cyclophosphamide, ifosfamide and trofosfamide against [mouse] leukemia L1210 in vivo suggests a superior effect for the ifosfamide derivative.
