描述

一般說明

A superior reagent for rapid and effective coupling of N-methyl amino acids with low enantiomerization and for other critical applications ^{[1,2,3,4,5,6,7,8]}. The coupling of N-methyl amino acids is difficult, and usually only gives low to moderate yields of products which are often contaminated with unwanted diastereomers. Many coupling reagents are ineffective or not practical to use: BOP and HOBt are often useless; BOP-Cl, pivaloyl chloride and Dpp-Cl require long reaction times and preactivation at 0°C.For coupling γ-aminoisobutyric acid (Aib), PyBrOP^® is most effective when used with dimethylaminopyridine (DMAP) ^[3].
