Amino alcohols have been used to introduce non-racemic chirality into macrocycles using a modular approach that relies on a Heck macrocyclisation reaction. A wide variety of macrocycles have been synthesised, and their structures studied using X-ray crystallography and molecular modelling. A fragmentation reaction encountered during the use of (S)-1,1-dimethylvalinol revealed that carboxylic acids
使用依赖于Heck大环化反应的模块化方法,氨基醇已用于将非外消旋手性引入大环。合成了各种各样的大环,并使用X射线晶体学和分子建模研究了它们的结构。在使用(S)-1,1-二甲基戊醇期间遇到的断裂反应表明,羧酸在经常用于Heck反应的反应条件下生成酰基。
