New convergent synthesis of natural α-substituted-β-carbolines, e.g. I (R = Ph, 2-pyridyl, Me, 2-quinolinyl) through metalations, cross-couplings and intramol. substitution via (2-aminobenzene)boronic acid, arylstannanes and 3,4-fluoroiodopyridines was achieved. Thus, 2,2-dimethyl-N-[2-(2-chloro-3-fluoro-4-pyridyl)phenyl]propanamide (II, R = Cl), prepared in 3 steps form 3-amino-2-chloropyridine, was coupled with 2-(trimethylstannyl)quinoline to give II (R = 2-quinolinyl), which was cyclized by treatment with pyridinium chloride to give I (R = 2-quinolinyl).
Tetrahedron published new progress about 146140-95-6. 146140-95-6 belongs to amides-buliding-blocks, auxiliary class Boronic acid and ester,Amine,Benzene,Amide,Boronic Acids,Boronic Acids,Boronic acid and ester,, name is (2-Pivalamidophenyl)boronic acid, and the molecular formula is C11H16BNO3, Category: amides-buliding-blocks.
