Aryl carbamate oligomers for hydrolyzable prodrugs and prodrugs comprising same

The present invention provides a compound having a formula: where R 1 is selected from the group consisting of alkyl, CH 2 (OC 2 H 4 )OCH 3 , and —(OC 2 H 4 )OCH 3 ; n is 0-4; Olig is an oligomer having a formula: -L-O-PAGR.R 2 ] q where L is a optional linker moiety selected from the group consisting of —CH 2 O—, —CH 2 OX—, —OX—, —C(O)—, —C(O)X, —NH—, —NHC(O)—, —XNHC(O)—, —NHC(O)X—, —C(O)NH—, —C(O)NHX—, and where X is alkyl 1-6 or is not present, Y is N or O or is not present, and R 3 is alkyl 1-6 ; PAG is a linear or branched polyalkylene glycol moiety; R 2 is an alkyl 1-22 capping moiety if X is present or alkyl 2-22 if X is not present; and q is a number from 1 to the maximum number of branches on PAG; and m is 1-5.
