- Perhydrolysis in Ethereal H2O2 Mediated by MoO2(acac)2: Distinct Chemoselectivity between Ketones, Ketals, and Epoxides
-
Ketones, ketals, and epoxides were converted into corresponding hydroperoxides in high yields by reaction with ethereal H2O2 in the presence of a catalytic amount of MoO2(acac)2 with distinct (to date unattainable) chemoselectivity.

- Simplified analogues of qinghaosu (artemisinin)
-
Three new simplified analogues of qinghaosu have been designed and synthesized through simple routes without recourse to the commonly employed photosensitized oxidation. The peroxy bonds in the target molecules were taken from UHP with the first peroxy-ca

- Intramolecular anodic olefin coupling reactions: The use of bis enol ether substrates
-
In an effort to develop electrochemical methods for directly initiating oxidative cyclization reactions, the anodic oxidation of bis enol ether substrates has been examined. The reactions were found to lead to the formation of five-, six-, and seven-membered-ring 1,4-dicarbonyl equivalents. The reactions were not found to be useful for generating larger ring sizes. Both alkyl and silyl enol ether substrates were found to be compatible with the conditions required for carbon-carbon bond formation. Cyclic voltammetry studies indicated that the cyclizations were fast and that the reactions happened at or near the electrode surface. Finally, the cyclization reactions were shown to be compatible with the formation of quaternary carbons, even when carbon-carbon bond formation involved the generation of two vicinal quaternary carbons.
