摘要
A facile synthesis of 1,3,4-oxadiazoles and 1,3,4-oxadiazoles-d_(5) via[4+1]cyclization of ClCF_(2)COONa with non-amine compounds containing amino groups is developed.Of note,this is the first time that halofluorinated compounds are used as C1 synthon to construct deuterated nitrogen-heterocyclic compounds.The current protocol features simple operation,readily accessible raw materials,wide substrate scope and valuable products.
