Pyrylium tetrafluoroborate is used for the functionalization of heterocyclic amines, activating them for nucleophilic substitution. As demonstrated by the Cornella lab, the intermediate pyridinium salts can react with a vast array of nucelophiles to form new C-N, C-O, and C-S bonds, making pyrylium tetrafluoroborate a valuable reagent for late-stage functionalization.

The functionalization of aminoheterocycles by using a pyrylium tetrafluoroborate reagent (Pyry-BF4 ) is presented. This reagent efficiently condenses with a great variety of heterocyclic amines and primes the C-N bond for nucleophilic aromatic substitution. More than 60 examples for the
The main focus of the Cornella research group is the development of rapid, practical and efficient methodologies for organic synthesis. In addition to efficiency and practicality, the group is highly interested in discovering new reactivity with the aim of unveiling novel transformations. More specifically, on the fundamental understanding and application of catalytic processes and the development of simple reagents. These two approaches have enormous potential and impact across the chemical sciences.
