utilized as complementary precursors for the synthesis of important heterocycles. The synthesis of N-substituted benzimidazoles was possible from the palladium-catalyzed reaction of both classes of substrate with a variety of N-nucleophiles. The use of the imidate precursor for the synthesis of N-substituted quinazolinones by incorporation of a palladium-catalyzed aminocarbonylation reaction has also been
N-(邻卤代苯基)亚氨基酰氯和相应的酰亚胺化物易于制备,并且可用作合成重要杂环的互补前体。N-取代的苯并咪唑的合成可能是由两类底物与多种N-亲核试剂的钯催化反应所致。还已经证明了亚氨酸酯前体通过掺入钯催化的氨基羰基化反应用于合成N-取代的喹唑啉酮的用途。两种方法都可以耐受各种官能团。
