Marfey’s derivatization studies) and the total synthesis of a novel antimalarial lipid-peptide isolated from Streptomyces sp. (IC50 = 0.8 μM, Plasmodium falciparum 3D7) is disclosed. To this end, versatile stereocontrolled routes to nonproteinogenic amino acids (via catalytic Mannich, Sharpless methods) and enantiomeric trans fatty acids (via Evans alkylation, Kocienski–Julia olefination) have been
绝对构型(通过降解和Marfey的衍生化研究)和从链霉菌属分离的新型抗疟疾脂肽的总合成。公开了(IC 50=0.8μM,恶性疟原虫3D7)。为此,已经开发了多种非立体氨基酸途径(通过催化曼尼奇,Sharpless方法)和对映体反式脂肪酸(通过埃文斯烷基化,科辛斯基-朱莉亚烯化)的立体控制途径。
