Abstract

The oxidation of N-phenyltetrahydroisoquinolines occurs rapidly with DDQ. Under ambient conditions and in the presence of nitromethane, the corresponding β-nitroamine derivatives are isolated in good to excellent yields. Variation in the electronic nature of the isoquinoline and the N-phenyl substituent showed that a broad range of substituents are tolerated, with electronic communication between the isoquinoline aromatic ring and the C1 carbon ...
