Various primary amides and ketoamides have been obtained in good yields in a two-step reaction sequence. The first step involves the synthesis of aryl/alkenyl N-tert-butyl amides and aryl N-tert-butyl ketoamides from the corresponding iodides via palladium-catalysed carbonylation in the presence of t-BuNH2 as the nucleophile. Carbonylation was followed by selective cleavage of the t-Bu group using
在两步反应序列中,已经以高收率获得了各种伯酰胺和酮酰胺。第一个步骤涉及的芳基/烯合成Ñ -叔丁基酰胺和芳基ñ -叔丁基酮酰胺从通过在存在钯催化的羰基的相应的碘化物吨-BuNH 2作为亲核试剂。羰基化之后,使用TBDMSOTf作为试剂选择性切割t- Bu基团。
