A series of 2-substituted 1, 3-propanediol dicarbamates, related chemically to meprobamate, has been prepared for central riervoiis system pharmacological investigation. The Y- uiisubstitiited propaiiediol dicarbamates were obtained by an ester-exchange reaction bet~ ween the corresponding diol niid nrethan, by phosgenation of the diol followed by amnioiiiatiori of the bis (ch1orocarboriate) derivative, by the reaction of the diol with cyanic ...
