A series of 2-oxo or 2-thioxo 1,3-disulfonyl-1,3,2-diazaphospholidines 4 was prepared by condensation of phosphonyl dichlorides 2 with bis-N,N′-sulfonylethylenediamines 1 in pyridine. Complete aminolysis or alcoholysis of heterocycles 4 took place with regeneration of sulfonyldiamines 1. These reactions are very sensitive to steric hindrance, and hydrolysis is generally favoured over aminolysis. The results are discussed in terms of mechanisms of phosphorylation.
