decarboxylative amidation of α-ketoacids by using inexpensive tert-butyl hydroperoxide (TBHP), which is characterized by high yields, a broad substrate scope, mild reaction conditions, and a unique chemoselectivity. These features enable the synthesis of peptides from amino acid derived α-ketoacids under preservation of the stereochemical information.
迄今为止,酰胺键形成的策略,即有机合成中最基本和最重要的转变之一,主要集中在脱水反应上。在本文中,我们报告并证明了通过使用廉价的叔丁基氢过氧化物(TBHP)来生产α-酮酸的新型脱羧酰胺化技术的实用性,该技术的特点是收率高,底物范围宽,反应条件温和以及独特的化学选择性。这些特征使得能够在保留立体化学信息的情况下从氨基酸衍生的α-酮酸合成肽。
