An optimized solid-phase strategy for the preparation of the cyclic lipononadepsipeptide [N-Mst(L-Ser1), D-Ser4, L-Thr6, L-Asp8, L-Thr9]syringotoxin is reported. The strategy is based on the use of a mild orthogonal protection scheme and the incorporation of the nonproteinogenic amino acid (Z)-Dhb into the peptide chain as the dipeptide Fmoc-Thr(tBu)-(Z)-Dhb-OH. The didehydrodipeptide was synthesized
报道了一种用于制备环状脂腺苷肽[N-Mst(L-Ser1),D-Ser4,L-Thr6,L-Asp8,L-Thr9]丁香毒素的固相优化策略。该策略基于使用温和的正交保护方案,以及将非蛋白原性氨基酸(Z)-Dhb作为二肽Fmoc-Thr(tBu)-(Z)-Dhb-OH掺入肽链。通过水溶性碳二亚胺诱导的β-消除的保护性二肽合成双脱氢二肽,该保护性二肽含有Thr残基,其游离羟基侧链未被保护。
