An investigation of methods to efficiently prepare activated N-methylcarbamates is reported. N-(Methylcarbamoyloxy)succinimide (3a), aryl N-methylcarbamates 3b-d and 2,2,2-trifluoro-1-(trifluoromethyl)ethyl N-methylcarbamate (3e) have been prepared in 70-80% yields from the corresponding chloroformates 5a-e, which were prepared as crystalline solids by the condensation of trichloromethylchloroformate (1) or bis(trichloromethyl)carbonate (2) with hydroxy compounds 4a-e in high yields.

A practical and convenient method for synthesizing antitumor compounds, N-alkyl-N-nitrosoureas, regioselectively nitrosated on the nitrogen atom bearing the alkyl group is proposed.N-Alkyl-N-nitrosocarbamates are interesting intermediates in these syntheses and yield, by reaction with amino compounds, the regioselectively nitrosated N-alkyl-N-nitrosoureas.As an interesting example, N,N'-biscystamine, a new attractive oncostatic derivative, has been prepared.The cytotoxic activity of these various compounds were tested on L1210 leukemia.
