chemoselective transformation of amines to their tert-butyloxycarbonyl (Boc) protected derivatives (NBoc) is described using Cu-NPs under solvent-free conditions. Simple method, rapid reaction rate, mild conditions, tolerance of a wide range of functional groups, excellent yield, ease recovery and high catalytic turnover are the salient features of this approach. tert-Butyloxycarbonylation of chiral amino acid
描述了在无溶剂条件下使用Cu-NPs将胺化学选择性转化为叔丁氧羰基(Boc)保护的衍生物(N Boc)的过程。简单的方法,快速的反应速率,温和的条件,对各种官能团的耐受性,优异的收率,易于回收和高催化转化率是该方法的主要特征。手性氨基酸酯和氨基醇的叔丁氧基羰基化反应没有外消旋作用。
