reaction to include amine nucleophiles to form C–N bonds through the utilization of N-heterocyclic phosphine-butane (NHP-butane) has been developed. Both aliphatic alcohols and benzyl alcohols are suitable substrates for C–N bond construction. Various acidic nucleophiles such as benzoic acids, phenols, thiophenol, and secondary sulfonamide also provide the desired products of esters, ethers, thioether
已经开发出一种新的方案,该方案通过利用N-杂环膦-丁烷(NHP-丁烷)扩展了Mitsunobu反应的范围,使其包括胺亲核试剂以形成C–N键。脂族醇和苄醇都是适合于C–N键结构的底物。各种酸性亲核试剂(例如苯甲酸,苯酚,苯硫酚和仲磺酰胺)也可提供所需的酯,醚,硫醚和叔磺酰胺产物,产率为43-93%。重要的是,在这种Mitsunobu反应体系下,由市售胺一步合成了含C–N键的药物Piribedil和Cinnarizine。
