Abstract
Methods for synthesis of 1-(acyloxy)-alkyl carbamates, particularly, the synthesis of 1-(acyloxy)-alkyl carbamate prodrugs of primary or secondary amine-containing drugs are described. Also described are methods for synthesis of 1-(acyloxy)-alkyl N-hydroxysuccinimidyl carbonates which are useful intermediates in the synthesis of 1-(acyloxy)-alkyl carbamates are also described.
