We investigated the phosphorylation and thiophosphorylation of 2-thiazolidine- and 2-oxazolidine-thiones. The presence in the heterocycle of the ambident triad HN-C=S can also lead to two series of phosphorylation products formed at the nitrogen and at the sulfur atom. It was therefore of interest to determine the dependence of the site of the phosphorylation on the structures of the heterocycle and off the phosphorylating agent. The formation of the N-phosphorylation products is confirmed by the /sup 1/H NMR spectra, in which the signals of protons of the methylene group of the heteroring (C/sup 4/H/sub 2/) are split on account of interaction with the phosphorus atom (/sup 3/JPH 0.5-2.3 Hz). We observed analogous values of /sup 3/JPH constants for 2-aminothiazolines phosphorylated on the endocyclic nitrogen atom. In the /sup 13/C NMR spectra of these compounds there are also coupling constants for the interaction of the carbon atoms C/sup 4/ and C/sup 5/ of the heterocycle with the phosphorus atom. The existence of the compounds as N-phosphorylated heterocycles is evidenced also by the /sup 31/P chemical shifts.
