Ionic hydrogenation of naphthyl tetrafluoropyridin-4-yl ethers as a new route to 5,6,7,8-tetrahydronaphthols
摘要:
O-Tetrafluoropyridin-4-yl-protected naphthols undergo regioselective reduction with cyclohexane in the presence of aluminium chloride to afford the corresponding 5,6,7,8-tetrahydronaphthyl ethers.
influence reaction regioselectivity remote to their local chemical environment are not widely reported in the literature. Herein, we report the development of remote regioselective electrophilic aromatic substitution (SEAr) reactions that are enabled via the application of the tetrafluoropyridyl (TFP) phenol-protecting group. We demonstrate that through sequential reactions and protection/deprotection of
