固相有机合成(SPOS)是高通量平行合成或组合合成化合物库的重要方法.然而,在构建一个化合物库前,常常缺少可以对反应历程进行实时(real-time)监测的简单、快速的分析方法.傅里叶变换红外光谱(FTIR)对有机官能团的改变非常灵敏,通过观察特征官能团吸收信号的出现与消失,可检测化学反应是否发生.
The solid-phase synthesis of 7-fluoro-1,4-2H-benzoxazine 3 (4H)-ones on Wang resin via esterification, etherification, reduction, cyclization and cleavage reactions was studied, and the reaction conditions were optimized after analyzing the reaction kinetics according to the IR spectrum.
