Synthesis of 2-substituted furanonaphthoquinones using directed metalation and cross coupling reactions

A synthetic method for the preparation of C-2 substituted furanonaphthoquinones from ortholithium-benzamide and the 2-furan- carboxaldehyde derivative is described. Four 2-alkyl-furanonaphthoquinones and the 2-phenyl-substituted were prepared via phathalide. This route has been shown to be general application to the synthesis of furanonaphthoquinones.

THE SYNTHESIS OF 2,5-DISUBSTITUTED FURANS

The dianion derived from the oxime of furfuraldehyde (1) reacts with electrophiles at the 5-position of the furan ring; subsequent hydrolysis of the oxime provides a useful method for the synthesis of 2,5-disubstituted furans.
