to run: A new one‐pot multicomponent reaction involving the use of an aldehyde, a cyanoacid derivative, and the Bestmann–Ohira reagent (BOR) has been developed for the synthesis of substituted phosphonyl pyrazoles. This process was also combined with a copper‐catalyzed azide–alkyne 1,3‐dipolar cycloaddition to generate five new bonds and two heterocyclic rings in a one‐pot fashion.
即将运行的BOR-n:已开发出一种新的单锅多组分反应,该反应涉及使用醛,氰酸衍生物和Bestmann-Ohira试剂(BOR)来合成取代的膦酰基吡唑。此过程还与铜催化的叠氮化物-炔烃1,3-偶极环加成反应相结合,以一锅法生成五个新键和两个杂环。
