Palladium-Imidazolium Carbene Catalyzed Heck Coupling Reactions and Synthesis of a Novel Class of Fluoroanthracenylmethyl PTC Catalysts
… level of utility using various catalysts, conditions and substrates. Yet significant drawbacks remain, including poor reactivity, the need for high temperatures and base, limited substrate generality, and selectivity. Mixed products often suffer from olefin migration following insertion. …

New applications of Imidazotetrazinone prodrugs. Synthesis and mechanistic investigation of novel imidazotetrazinones as prodrugs of aziridines and as traceless carriers for drug delivery to the central nervous system.
… in their structures to release aziridinium ions upon ring opening. Unstable 2-aminoethylisocyanates were required in this preparation, which were synthesized with BOC-protection of the amino group to counteract the reactivity of the amine towards the isocyanate group in the case of aliphatic …
