吗啉杂环是许多生物活性化合物和 FDA 批准的药物中发现的结构单元,但更复杂的 C 官能化吗啉衍生物的生成仍远未得到充分探索。利用系统化学多样性(SCD)这一概念,通过区域化学和立体化学变化指导饱和类药物支架的扩展,我们描述了从对映体纯氨基酸和氨基醇开始合成一系列甲基取代吗啉乙酸酯。总共产生了 24 种不同的取代吗啉,它们在区域化学和立体化学(相对和绝对)上系统地变化。这些不同的 C 取代吗啉可直接应用于片段筛选或作为药物化学和文库合成的构建模块。

A four-step synthesis of cis-3,5-disubstituted morpholines from enantiomerically pure amino alcohols is described. The key step in the synthesis is a Pd-catalyzed carboamination reaction between a substituted ethanolamine derivative and an aryl or alkenyl bromide. The morpholine products are generated as single stereoisomers in moderate to good yield. This strategy also provides access to fused bicyclic
