A series of acyclic sulfamates have been prepared and tested for antimicrobial activity. Thus, the oxysulfonyl isocyanates, ROSO2NCO (1a, R = 4-methoxyphenyl; 1b, R = phenyl; 1c, R = 4-chlorophenyl and 1d, R = 2,2,2-trifluoroethyl) have been prepared in 76-91% yield from chlorosulfonyl isocyanate. Treatment of lad with glycidol gave the glycidyl carbamates 2a-d. Internal cyclisation afforded the corresponding 3-hydroxymethyl-2-oxazolidinones 3a d, which in turn were hydrolysed to give the free amino alcohols 4a-d. The yields were in the range 39-85%. A preliminary agar diffusion test of 2a-d, 3a d, 4a d indicated 2a-d and 3e to be possible antimicrobial agents. A more thorough analysis of these compounds revealed a minimum inhibition concentration (MIC) of 128 and 64 mg 1(-1) for glycidyl p-methoxyphenoxysulfonylcarbamate (2a) and glycidyl phenoxysulfonylcarbamate (2b) respectively, against Branhamella catarrhalis.
