title: [Reaction of pyridinium salts with active methylene compounds].
abstract: The carbon-carbon bond-forming reactions of 1-methyl-2-methylthiophenylpyridinium iodides with active methylene compounds (such as dimethyl malonate, malononitrile) using NaH as a base gave the 2-substituted methylene-1,2-dihydropyridine derivatives.
