sphonate [DPPOx] has been newly introduced as a carboxyl-activating reagent which permits a facile direct preparation of 3-acyl-2-oxazolones and amides including peptides from a wide variety of carboxylic acids The 3-acyl-2-oxazolides also serve as versatile reactive agents for highly chemoselective acyl-transfer to the nucleophilic species such as amines, alcohols and thiols, providing convenient
描述了2-恶唑酮部分作为优异的新离去基团的合成效用。基于杂环的这种功能,新引入了2-氧代-3-恶唑啉基膦酸二苯酯[DPPOx]作为羧基活化剂,可以轻松地直接制备3-酰基-2-恶唑酮和酰胺,包括各种羧酸3-酰基-2-恶唑内酯还用作通用的反应剂,可高度化学选择性地将酰基转移至亲核物质,例如胺,醇和硫醇,为酰胺,酯和硫醇的制备提供了便捷且高产的途径酯在温和的条件下。它们也是酮和醇的有用中间体。
