REGIOSELECTIVE ADDITION OF TITANIUM ENOLATES TO 1-ACYLPYRIDINIUM SALTS. A CONVENIENT SYNTHESIS OF 4-(2-OXOALKYL)PYRIDINES
Comins, Daniel L.,Brown, Jack D.
, p. 3297 - 3300 (2007/10/02)
Titanium enolates add to the 4-position of 1-phenoxycarbonylpyridinium salts to give 1,4-dihydropyridines; subsequent aromatization provides 4-(2-oxoalkyl)pyridines.
