Project Description:
Sterically hindered anilines are important to medicinal chemists due to their ability to increase the lipophilicity and
metabolic stability of drug molecules. Current methodologies for the synthesis of hindered anilines often require
harsh basic and acidic conditions and can be limited by over alkylation. We utilize a new methodology that
overcomes these drawbacks and uses readily available starting material and abundant copper salt catalysts in a
radical coupling reaction. We synthesize sterically hindered anilines through a radical mediated coupling process
using alkyl halides and nitrosoarenes. This reaction occurs under mild reaction conditions with high functional
group tolerance. We are currently developing an intramolecular process to access amino alcohols of various
substituents. Currently we have synthesized amino alcohols utilizing the following nitroso compounds: 1-methoxy-
4-nitrosobenzene, methyl 4-nitrosobenzoate, 1,3-dimethyl-5-nitrosobenzene, 1-iodo-2-nitrosobenzene, 1-chloro-3-
nitrosobenzene, and 1-bromo-4-nitrosobenzene. The compounds are purified using column chromatography and
characterized using NMR, Mass Spectroscopy and IR. We anticipate constructing a library of small molecules with
a variety of functional groups using this process. This work will be applied in synthesizing new pharmaceutical
drugs.
