A New Route to Naphthofuran-4,9-diones from Thio-substituted 1,4-Naphthoquinones

Kang, Wen-Bing,Sekiya, Takashi,Toru, Takeshi,Ueno, Yoshio

, p. 441 - 445 (2007/10/02)

Reaction of 2-phenylthio- or 2-ethylthio-1,4-naphthoquinones (1) and (2) with lithium enolates or pyridinium ylides was found to give alkylated 1,4-naphthoquionones (3)-(6) in high yields.Alkylated 1,4-naphthoquinones (5) and (6) were then effectively cyclized to 2-substituted naphthofuran-4,9-diones (8) by action of bromine in acetic acid.
