A two-step macrocyclization strategy for the synthesis of 12- and 14-membered cyclic peptidotriazoles by combining a one pot four-component reaction and an intramolecular [3+2] azide–alkyne click cycloaddition reaction is described. Macrocycles are obtained in good to excellent yield from the aqueous work-up of the reaction mixture and it is possible to expand or contract the ring size by adjusting
描述了通过结合一锅四组分反应和分子内[3 + 2]叠氮化物-炔键环加成反应来合成12和14元环肽三唑的两步大环化策略。从反应混合物的水后处理中以良好或优异的收率获得大环化合物,并且可以通过调节MCR阶段中使用的腈部分的长度来扩大或缩小环的尺寸。
