Article abstract of DOI:10.1246/cl.1996.451

A one-step formation of furoquinones, such as naphtho[2,3-b]furan-4,9-dione, naphtho[1,2-b]furan-4,5-dione, benzofuran-4 4,7-dione, and benzofuran-4,5-dione derivatives, by the ceric ammonium nitrate mediated [3+2] type cycloaddition of 2-hydroxy-1,4-naph
