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.

The Synthesis of Functionalized Dimethylphosphinoyl Cyclopropanes and Cyclobutanes
Журнал органічної та фармацевтичної хімії, 2023 A simple preparative approach to a series of functionalized dimethylphosphinoyl-containing cyclopropanes and cyclobutanes has been developed; it is based on cyclocondensation of dimethylphosphinoyl acetonitrile with 1,2- and 1,3-dibromoalkanes. Synthetic
