(ATPC) is an unnatural amino acid with promise in applications as a building block for the synthesis of peptidomimetics. ATPC was obtained from both 3a and 3b thienopyrimidines by hydrolysis and hydrogenolysis, respectively. The synthesis of eleven ATPC-amino acids and two ATPC-peptides is described. ATPC is incorporated as N-terminal moiety in solution or solid-phase peptide synthesis using Boc or
2-Amino-4-pyrrolidinothieno[2,3-d]pyrimidine-6-carboxy acid (4) (ATPC) 是一种非天然氨基酸,有望作为合成肽模拟物的构件。ATPC 分别通过水解和氢解从 3a 和 3b 噻吩并嘧啶中获得。描述了十一种ATPC-氨基酸和两种ATPC-肽的合成。使用 Boc 或 Fmoc 方法将 ATPC 作为 N 端部分引入溶液或固相肽合成中,而无需保护 ATPC 氨基。
