macrocyclisation approach based on the double aromatic nucleophilic substitution (SNACK) was developed. This methodology allows a facile incorporation of heterocyclic motifs into macrocyclic rings and rapid synthesis of a significant number of structurally diverse macrocycles. SNACK macrocyclisation enables preparation of stable diastereoisomers of conformationally restricted macrocycles (atropisomers). Practical
                                    开发了一种基于双芳香族亲核取代(S
NACK)的有效大环化方法。该方法允许将杂环基序轻松掺入大环中,并快速合成大量结构多样的大环。 S
NACK 大环化能够制备构象限制大环的稳定非对映异构体(阻转异构体)。 B 细胞淋巴瘤 6 (BCL6) 的高亲和力大环结合剂的鉴定例证了 S
NACK 大环化在药物发现项目中的实际应用。
