Preparation and reactions of stable 2-lithio-6-nitrophenol derivatives

Add time:08/16/2019    Source:sciencedirect.com

2-Bromo-6-nitrophenyl MOM and SEM ethers from stable lithio compounds on treatment with phenyllithium. Reaction of the lithio species with a variety of electrophiles allows the preparation of 2-substituted-6-nitrophenols. The intramolecular trapping of (2′,3′-epoxypropyloxy)-2-lithio-4-methyl-6-nitrobenzene gives the substituted benzofuran (5).
