摘要：
BOR-n 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.
