Aminolysis of N-Tritylamino Acid Benzotriazolyl Esters with Concentrated Aqueous Amines and its Applications in Synthesis.
摘要:
Aminolysis of (S)-N-tritylamino acid benzotriazolyl esters with concentrated aqueous amines produces high yields of the corresponding amides which can be readily detritylated with p-toluensulfonic acid or reduced with lithium aluminium hydride to provide chiral ethane-1;2-diamine derivatives.
