Gujjarappa, Raghuram; Vodnala, Nagaraju; Musib, Dulal; Malakar, Chandi C. published the artcile< Organocatalytic Decarboxylation and Dual C(sp3)-H Bond Functionalization Toward Facile Access to Divergent 2,6-Diarylpyridines>, Electric Literature of 350-03-8, the main research area is diarylpyridine preparation; ketone amino acid decarboxylation proline catalyst.
An effective organocatalytic protocol toward the assembly of sym. and unsym. 2,6-diarylpyridines I (R1 = H, Me, CN; R2 = Ph, 4-methylphenyl, 2H-1,3-benzodioxol-5-yl, etc.; R3 = Ph, 4-nitrophenyl, pyridin-3-yl, etc.) is demonstrated. The reaction proceeds through organocatalytic decarboxylation of amino acids R4CH(NH2)C(O)OH and dual C(sp3)-H bond oxidation of carbonyl compounds R1CH2C(O)R2 and R1CH2C(O)R3. Catalyst screening revealed that explicit choice of L-proline could lead to the formation of product with maximum yield and selectivity. The developed process appears with operational simplicity and is consistent with broad range of functional groups.
