A simple method of generating naphtho[1,2-c]furan and naphtho[2,3-c]furan
Abstract
Naphtho[1,2-c]furan and the novel naphtho[2,3-c]furan have been generated from 2-(hydroxymethyl)-1-naphthaldehyde and 3-(hydroxymethyl)-2-naphthaldehyde, respectively, and trapped in Diels–Alder reactions with maleic anhydride.
