Abstract
N-Aminomethylation of 4,4-bis(chloromethyl)oxazolidin-2-one with formaldehyde and secondary amines is accompanied by the intramolecular ring closure to give 7a-chloromethyl3-oxohexahydroimidazo[1,5-c]oxazol-6-ium chlorides. In the case of the closely related 4,4-bis(acetoxymethyl)oxazolidin-2-one, only N-aminomethylation occurs.
