Abstract

Abstract : The organic superbase catalyst tBu‐P4 assists methoxy‐alkoxy exchange reactions on (hetero)arenes with alcohols. The catalytic reaction proceeds efficiently with electron‐deficient methoxy(hetero)arenes, as well as a variety of alcohols, including 3‐amino‐1‐propanol, β‐citronellol, menthol, and cholesterol. An intramolecular version of this reaction furnishes six‐ and seven‐membered ring compounds. More information can be found in the Communication by M. Shigeno, Y. Kondo, et al. onpage 6077 .
