Abstract
In this article, the amido and hydroxyl of L-serine and L-tyrosine were protected using base-liable Fmoc group and acid-liable tert-butyl group respectively, and Fmoc -OSU could introduce Fmoc group while tert-butyl group was introduced by isobutene. Besides, the optimal reaction time, temperature and pH value were reported. The yield was enhanced than the literature reported and the purity was above 98%.
