Palladium-catalyzed regioselective silaboration of pyridines leading to the synthesis of silylated dihydropyridines

The addition of silylboronic esters to pyridine takes place in toluene at 50 °C in the presence of a palladium catalyst to give N-boryl-4-silyl-1,4- dihydropyridines in high yield. The regioselective 1,4-silaboration also proceeds in the reaction of 2-picoline and 3-substituted pyridines, whereas 4-substituted pyridines undergo 1,2-silaboration to give N-boryl-2-silyl-1,2- dihydropyridines regioselectively.

PREPARATION OF SUBSTITUTED 9,10-DIHYDRO-9-SILA-3-AZAANTHRACENES AND THEIR DERIVATIVES

3-Methyl-4-dimethylphenylsilylpyridine and 3-methyl-4-methyldiphenylsilylpyridine, which were obtained from β-picoline and dimethylphenylchlorosilane and methyldiphenylchlorosilane, respectively, were coverted by catalytic dehydrocyclization to 9,9-dimeth
