Asymmetric Alkylation of Amide Enolates with Pseudoephedrine and Ephedrine as Chiral Auxiliaries—Unexpected Influence of Additives? 来自 国家科技图书文献中心 喜欢 0 阅读量: 27 作者:Karola,Rück 摘要: The self-assembly of enolates can be controlled by the addition of nonstoichiometric amounts of ...
(23), an amide possessing N–H bonds (24,25) and a base-sensitive ketone (26) were well tolerated. This reaction could also be conducted in the presence of an aryl chloride (27), an alkyl chloride (28) and an aryl bromide (29), thus providing an exceptional opportunity for further ...
Amides are a fundamental and widespread functional group, and are usually considered as poor electrophiles owing to resonance stabilization of the amide bond. Various approaches have been developed to address challenges in amide transformations. Nonethel

Appropriate bases are, respectively, sodium amide generated in ammonia and sodium hydroxide or sodium hydride in the case of DMSO. Although not included in preparative studies which the author has encountered, it seems likely that potassium t-butoxide in THF would also give satisfactory results, ...
