The preparation of (oxodioxolenyl) methyl carbamates and their evaluation as novel nonchiral prodrug moieties for chiral primary and secondary amino functional drugs are described. 4-(Carbamoylmethyl)-2-oxo-1, 3-dioxolene derivatives of 3, 4- dimethoxyphenethylamine with 5-methyl, 5-phenyl, and 5-anisyl substitution (5a, 5b, and 5c) on the dioxolenone ring were prepared as model amine prodrugs by a one step process ...
