2-Cyano-1-pyrroline 1-oxides (1) could not be converted directly into the related cyclic thiohydroxamic acids (8). Potassium ethyl xanthate transformed nitrones (1) into the imidates (2). The cyclic hydroxamic acids (4) can be converted into the thiohydroxamic acids (8) via the methoxypyrrolidinones (5) and the methoxypyrrolidine thiones (6), making use of sodium p- tolylmercaptide as the demethylating agent. Reaction of methoxy thiones (6) with trimethylsilyl iodide led to the formation of the 2-methylthio-1-pyrroline 1-oxides (7).
