  Pyrrole Synthesis Catalyzed by AgOTf or Cationic Au(I) Complexes

  摘要：

  Either silver trifluoromethanesulfonate or a mixture of gold( I) chloride, silver trifluoromethanesulfonate, and triphenylphosphine catalyze the formation of pyrroles from substituted beta-alkynyl ketones and amines. The reactions proceed by using 5 mol % of catalyst with yields of isolated pyrroles ranging from 13% to 92%. Sixteen examples are used to compare the effectiveness of each catalyst.

  日期：——

  The reaction of N-acylated isofebrifugine with hydrochloric acid is discussed. Although the corresponding deprotected compound was not isolated, three new heterocyclic compounds were obtained. Based on these findings, new furan and pyrrole derivatives were prepared.
