A one-pot Barluenga coupling between N-tosylhydrazones and nitro-benzyl bromide, followed by deoxygenation of ortho-nitrostyrenes, and subsequent cyclization has been developed, providing a new way to synthesize various C2-arylindoles. This method exhibits a good substrate scope and functional group tolerance, and it allows an access to NH-free indoles, which can present a potential utility in medicinal
已开发出N-甲苯磺酰hydr和硝基苄基溴之间的一锅Barluenga偶联,然后对邻硝基苯乙烯进行脱氧,然后进行环化,为合成各种C2-芳基吲哚提供了新途径。该方法表现出良好的底物范围和官能团耐受性,并且允许接触不含NH的吲哚,这可能在药物化学应用中具有潜在的实用性。
