摘要：本文描述了在异氰化物催化下，四氰乙烯与各种活化的CH -酸化合物在室温下几分钟内以高收率生成相应的吡喃环杂环体系的反应。据我们所知，这是异氰化物仅作为催化剂而不作为试剂的第一个例子。
Abstract An isocyanide‐catalyzed reaction between tetracyanoethylene and various activated CH‐acid compounds to afford the corresponding pyran annulated heterocyclic ring systems, in high yield at room temperature within a few minutes, is described. To the best of our knowledge, this is the first example in which isocyanide functions as only a catalyst but not a reagent.
