The synthesis of two new furyl amino acids as rigid isosteres of the dipeptides (D)-H-Ser-(D,L)-Thr-OH and (L)-H-Ser-(D,L)-Thr-OH is presented. The developed synthetic methodology starts from D-xylose and D-arabinose and makes use of trihydroxypropylfurans as intermediates. The key step of the strategy is the introduction of an amino function at the α-position of the adequate trihydroxypropylfuran
作为二肽 (D)-H-Ser-(D,L)-Thr-OH 和 (L)-H-Ser-(D,L)-Thr-OH 的刚性等排体的两种新呋喃基氨基酸的合成是呈现。开发的合成方法从 D-木糖和 D-阿拉伯糖开始,并使用三羟丙基呋喃作为中间体。该策略的关键步骤是在适当的三羟丙基呋喃衍生物的 α 位引入氨基官能团。该方法还应用于合成两种新的 (2R,3R)-3-呋喃异丝氨酸作为 C-13 紫杉醇/泰索帝侧链的类似物。
