The Ni-formy protecting group of tryptophan in solidphasepeptidesynthesis was found to be removed efficiently and quantitatively by a new reagent, HF–Me2S–p-thiocresol–p-cresol (25: 65: 5: 5, v/v/v/v) without detectable side reaction.
所述Ñ我-formy保护在固相肽合成色氨酸组被发现可以通过一个新的试剂,HF-ME有效且定量地除去2 S- p -thiocresol- p甲酚(25:65:5:5,V / v / v / v),而没有可检测到的副反应。
