Catalytic methylnaphthyl(XPhos)-palladium bromide promotes the coupling of chiral tert-leucine-derived Schöllkopf bis-lactim ether with cheap aryl chlorides at room temperature in yields up to 95 % and >25 : 1 dr. This enables a convenient access to non-natural tertiary arylglycines, which are key structural motifs in several top-selling drugs. This protocol is also suitable for the late-stage functionalization
催化甲基萘基 (XPhos)-溴化钯可促进手性叔亮氨酸衍生的 Schöllkopf 双内酰亚胺醚与廉价芳基氯在室温下偶联,收率高达 95%,且博士 >25:1。这使得能够方便地获得非天然叔芳基甘氨酸,这是几种最畅销药物的关键结构基序。该协议也适用于常见药物的后期功能化。
