A rhodium-catalyzed formal [4+1]-cycloaddition of pyridotriazoles and aryl propargyl alcohols is reported, providing an effective access to 2-pyridyl-substituted 2,5-dihydrofuran derivatives in moderate to high yields. Mechanistically, the proposed oxonium ylide intermediate in this catalytic alkyne carbocyclization transformation is verified by an interception experiment for the first time. (Figure presented.).

Carbon nucleophiles generated by a non-nucleophilic base (LDA) were effectively trapped with di-tert-butyl dicarbonate (Boc-anhydride) to provide the corresponding tert-butyl aryl acetates, di-tert-butyl aryl malonates, unsymmetrical aryl malonates and te
