The syntheses of tris(2-nicotinic acid)methanol methyl ether 5 and tris(2-picolinic acid)methanol methyl ether 6, two tridentate ligands designed to also act as scaffolds for constructing chiral environments around their metal binding sites, is described. Improved yields for the essential lithiation–alkylation reactions that generate the trispyridyl core of these types of ligands are reported.
描述了三(2-烟酸)甲醇甲基醚5和三(2-吡啶甲酸)甲醇甲基醚6的合成,这两种三齿配体被设计为还充当在其金属结合位点周围构建手性环境的支架。据报道,产生这些类型的配体的三吡啶基核心的基本锂化-烷基化反应的收率得到提高。
