Abstract

magnified image In this study a facile synthesis of novel 10‐tert‐butyl[1]benzoxepino[3,4‐b][1,3]dioxolo[4, 5‐g]quinolin‐12(6__H__)‐ones is described, featuring the one‐pot synthesis of 6‐[(tert‐butylphenoxy)methyl][1,3]dioxolo[4,5‐g]quinoline‐7‐carboxylic acids from ethyl 6‐(bromomethyl)[1,3]dioxolo[4,5‐g]quinoline‐7‐carboxylate and their intramolecular Friedel‐Crafts acylation reaction by the use of Eaton's reagent (P~2~O~5~–CH~3~ SO~3~H) under mild conditions. J. Heterocyclic Chem., (2009).
