General description

2-(Pyridin-2-yl)isopropyl amine (PIP-amine) is a tertiary amine. A bidentate directing group, useful for the functionalization of C-H bond, has been developed from PIP-amine.

Application

The Shi Auxiliary is a powerful directing group for the hydroxylation of arenes through copper-mediated C-H activation. This useful auxiliary can be removed through acid-mediated hydrolysis and has shown to be done on gram-scale.
