Amine-Functionalized Polybutadiene Synthesis by Tunable Postpolymerization Hydroaminoalkylation
, 2023 Early transition metal-catalyzed hydroaminoalkylation is a powerful single-step method to selectively add amines to polybutadienes, offering an efficient strategy to access amine-functionalized polyolefins. Aryl and alkyl secondary amines were used with

Molecules, 2008 The purpose of this work is to review the published strategies for the productionof prodrugs of amines. The review is divided in two main groups of approaches: those thatrely on enzymatic activation and those that take advantage of physiological chemicalconditions for release of the drugs.
