A method for direct highly O-selective phosphitylation of amino alcohols by reagents containing a 4-nitrophenoxy or 2,4 dinitrophenoxy leaving group has been developed. This method provides mild reaction conditions to access O-phosphitylated amino alcohols. The flexibility of the synthesis is exemplified by the models of simple amino alcohols and of nucleosides containing unprotected NH2 groups.
开发了一种方法,通过含有4-硝基苯氧基或2,4-二硝基苯氧基离去基团的试剂,实现氨基醇的高度O-选择性膦酸化。这种方法提供了温和的反应条件,用于制备O-膦酸化氨基醇。合成方法的灵活性通过简单氨基醇和含有未保护NH2基团的核苷模型得以展示。
