Regioselective Control of the SNAr Amination of 5-Substituted-2,4-Dichloropyrimidines Using Tertiary Amine Nucleophiles
The SnAr reaction of 2,4-dichloropyrimidines,further substituted with an electron-withdrawing substituent at C-5, has selectivity for substitution at C-4. Here to the reaction of a secondary amine nucleophile at C-2. This <...

Nucleophilic aromatic substitutions enable diversity-oriented synthesis of heterocyclic atropisomers via non-atropisomeric intermediates
(SNAr) reactions can progress via non-atropisomeric intermediates and transition states. We put forth fast, mild, practical, regio- and chemoselective SNAr reactions in seconds. Products of SNAr are readi...

Construction of the carbon-chalcogen (S, Se, Te) bond at the 2,6-positions of BODIPY via Stille cross-coupling reaction
Seven new 2-chalcogen-or 2,6-dichalcogen-(S, Se, Te) BODIPY derivatives were synthesized in good to excellent yields (55-95%) by a Pd-catalyzed C-heteroatom Stille cross-coupling reaction, overcoming the limitations of SNAr. The flu...
