Reactions ofN,N-bis(chloromethyl)amides withN,N′-diacyl derivatives of ethylenediamine (oro-phenylenediamine) result in formation of the corresponding 1,3,5-triacylated perhydro-1,3,5-triazepines (or their benzoanalogs) or 1,3-diacylated imidazolidines (or their benzoanalogs). Reactions ofN,N-bis(chloromethyl)amides withN,N′-ditosylated trimethylenediamine occur in a similar way. The direction of the
N,N‐Bis(chlormethyl)carbonsäureamide 1 reagieren unter Ringschluß mit N,N'‐Dimethylhydrazin (2) zu 1,2,4‐Triazolidinderivaten 3 und mit 2‐Aminobenzothiazol (4) zu Abkömmlingen des Benzothiazolo‐1,3,5‐triazins 6.
