Abstract A copper or silver‐catalyzed cascade addition/5‐ exo‐dig cyclization/isomerization reaction of isothiocyanate with ynone has been developed. This strategy enables the synthesis a variety ( Z )‐2‐ylidene‐5‐aminothiophen‐3‐one derivatives diverse substitutions in single vessel. The method is featured pot‐economy as well regio‐ and ‐selectivity. Several biologically active molecules could be modified using this strategy. Moreover, relevant indole‐fused indole‐substituted thiophenone were also assembled one pot by merging other bond formation methods. Based on experiments related reports, pathway triggered addition ynone‐derived radical towards C( sp )‐atom was proposed to elucidate probable process transformation.

Abstract Difuropyridines have been prepared from aldehydes and chitin‐derived 3‐acetamidofuran (3AF) under acid‐catalyzed conditions. were comprehensively synthesized for the first time. The difuropyridines can be applied to prepare fluorescent probe analogs or catalyze decarboxylative reactions as photocatalysts.
