Myers’s methodology for enantioselective amino acid synthesis was employed to prepare the N-Boc didehydroleucine amide derivative 15 and to effect its conversion into the acylfuran intermediate 17. Coupling of 19 (R = H) with N-(isooctanoyl)serine provided the furan-based analogue 4 of eponemycin (de = 96 %), a peptide epoxide with potent cytotoxic and anti-angiogenesis properties. In an identical
Myers 的对映选择性氨基酸合成方法用于制备 N-Boc 双脱氢亮氨酸酰胺衍生物 15 并使其转化为酰基呋喃中间体 17。19 (R = H) 与 N-(异辛酰基)丝氨酸的偶联提供了基于呋喃的eponemycin 的类似物 4 (de = 96 %),一种具有有效细胞毒性和抗血管生成特性的肽环氧化物。以相同的方式制备了依泊霉素的相应不饱和类似物5(de = 48%)。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003
