标题:重氮化合物与芳基硼酸的催化性cc偶联:以表面改性的污水污泥为催化剂
摘要:通过高氯酸催化重氮化合物与芳基硼酸之间的偶联反应,开发了一种绿色,温和且高效的合成方法,该方法利用污水污泥衍生的碳质材料(sw)合成二芳基次甲基.该反应显示出高水平的功能耐受性和广泛的底物范围.此外,通过空间要求高的r 4,R 5提供了高选择性的1,2-烷基转移产物重氮化合物(3-重氮苯并二氢吡喃酮)的迁移.通过单晶x射线分析进一步证实了1,2-移位产物的结构.值得注意的是,Darifenacin(一种用于膀胱过度活动症的临床药物,Oab)和diclofensine(一种显示出抗抑郁和单胺再摄取抑制剂活性的兴奋剂)的核心结构的合成进一步证明了该方法的有效性和合成潜力.

标 题:Solid-phase synthesis of N-alkyl amides
发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.

摘要:Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.
