A one-pot synthesis of annulated heterocycles involving a Lewis-acid-mediated domino reaction of bis(diacetoxymethyl)-substituted arenes and heteroarenes is described. The reaction of the tetraacetates with arenes and heteroarenes leads to the formation of 1,1-bis-arylated diacetates upon elimination followed by electrocyclohetero-arylated intermediate may lead to the formation of bis-arylated 1,1-diacetates
描述了涉及双(二乙酰氧基甲基)取代的芳烃和杂芳烃的路易斯酸介导的多米诺反应的环状杂环的一锅合成。四乙酸酯与芳烃和杂芳烃的反应导致在消除后形成 1,1-双芳基化二乙酸酯,然后是电环杂芳基化中间体可能导致形成双芳基化 1,1-二乙酸酯,其在环化后芳构化提供环状杂环。
