4-dioxo-1,4-dihydronaphthalen-2-yl)methyl]-l-cysteine conjugates were obtained in good yields by acid-catalyzed condensation of substituted 2-hydroxy-1,4-naphthoquinones with N-acetyl-l-cysteine and paraformaldehyde. Based on this reaction, a first synthesis of fibrostatins B, C, and D was developed. A series of N-acetyl-S-[(3-hydroxy-1,4-dioxo-1,4-dihydronaphthalen-2-yl)methyl]-l-cysteine conjugates were
摘要 通过酸催化取代基的缩合反应,可以得到高收率的一系列N-乙酰基-S -[(3-羟基-1,4-二氧杂-1,4-二氢萘-2-基)甲基] -1-半胱氨酸结合物。 2-羟基-1,4-萘醌与N-乙酰基-1-半胱氨酸和多聚甲醛。基于该反应,开发了纤维抑素B,C和D的第一合成。 通过酸催化取代基的缩合反应,可以得到高收率的一系列N-乙酰基-S -[(3-羟基-1,4-二氧杂-1,4-二氢萘-2-基)甲基] -1-半胱氨酸结合物。 2-羟基-1,4-萘醌与N-乙酰基-1-半胱氨酸和多聚甲醛。基于该反应,开发了纤维抑素B,C和D的第一合成。
