Synthesis of benzofuran derivatives through the coupling of conjugated dienynes with Fischer carbene complexes

The reaction of Fischer carbene complexes with conjugated dienylacetylene derivatives followed by treatment with iodine leads to benzofuran derivatives in good-to-excellent yields. Equivalent products can be obtained from coupling of conjugated enediynes with Fischer carbene complexes in the presence of hydrogen atom donors.

Studies on Isocyanides and Related Compounds. Synthesis of Benzofuran Derivatives

The reaction between 2-hydroxybenzaldehyde (1a), isocyanides 2, and ammonium formate, in the conditions of the Ugi four-component condensation, affords 2-alkylamino- and 2-arylamino-3-[(2-hydroxybenzylidene)amino]benzofurans 3a-c. Analogously by employing 5-bromo-2-hydroxybenzaldehyde (1b) as the carbonyl compound, 2-alkylamino- and 2-arylamino-5-bromo-3-[(5-bromo-2-hydroxybenzylidene)amino]benzofurans 3d-f are obtained

Synthesis of Benzofuran Derivatives: One Pot Synthesis of 2(3H) Benzofuranones

Abstract Phenols are condensed with cinnamic acids in the presence of trifluoroacetic acid to give high yields of the corresponding 2(3H) benzofuranones.
