What is The cobalt way to vitamin B6 : Regioselective construction of the tetrasubstituted pyridine nucleus by cobalt-catalyzed alkyne-nitrile cooligomerizations about?

Ab@ract-Cocyclization of bisjtrimethylsilyl~ and bis(trimcthylstannyl)di-2propynyl ether with acetonitrilc provides a synthetic entry into 1,3dihydro-Gmethyl-4,7-bis(trimethylsilylh and bis(trimethylstanny1~ furo[3,4-c]pyridinea. Regioselective electrophiiic substitution of the rcspacdvc silyl or statinyl grotips allows for a regiooontrolled construction of tetrasubstituted pyridinrs. This method has been applied to a total synthesis of vitamin B,.
