protocol, which makes use of T3P as an acid activator for the synthesis of Nα-protected amino/peptide thioacids from corresponding acids in the presence of finely ground Na2S as hydrosulfide ion donor is described. The protocol employed significantly increases the overall efficiency as the yield, reaction duration and purity of even sterically hindered amino acids.
一般,轻度和高效的协议,这使得使用T3P作为酸活化剂用于合成Ñ α -保护的氨基/肽硫代酸在精细研磨的Na的存在相应的酸2为氢硫化物离子供体被描述S上。所采用的方案显着提高了整体效率,因为即使是位阻氨基酸也可以提高收率,反应持续时间和纯度。
