The first total synthesis and biological evaluation of the naturally occurring cyclic heptapeptide rhizonin A are described. The synthesis includes solution-phase peptide synthesis and the preparation of NMe-3-(3-furyl)alanine (NMe-FurAla), a unique component of rhizonin A, which was prepared in chiral form via Barton-MacCombie deoxygenation as a key step. The bioactivity was assessed using 3T3–L1
描述了天然存在的环状七肽根瘤菌素A的第一个全合成和生物学评估。合成包括溶液相肽合成和制备N Me-3-(3-呋喃基)丙氨酸(N Me-FurAla),这是根瘤菌素A的独特成分,它是通过Barton-MacCombie脱氧反应以手性形式制备的。关键步骤。使用3T3-L1鼠脂肪细胞评估生物活性。
