Nitrogen Containing Compounds

Nitrogen-containing compounds are an essential motif in all disciplines of chemistry and the efficient synthesis of these frameworks is a highly sought-after goal. Presented here is a summary of recent efforts conducted by our group to develop radical-mediated amination strategies for the formal synthesis of primary amines from alkenes with exclusive anti-Markovnikov regioselectivity. We have found that N-hydroxyphthalimide is an effective reagent capable of supplying both the N and H atoms for alkene hydroamination in a group transfer radical addition-type mechanism. Furthermore, allyl-oxyphthalimide derivatives are similarly capable of radical group transfers and allow for the aminoallylation of an external alkene.

Alkaloid Synthesis

An enantioselective formation of isoquinuclidines useful for alkaloid synthesis is achieved through an organocatalyzed Diels–Alder reaction of dihydropyridines with acrolein and a subsequent photoredox catalyzed oxidative deformylation reaction.
