A number of derivatives of indolizine ring system have been prepared from 1-substituted 4,6-diphenyl-2-phenacylidene-1,2-dihydropyridines either by metallation with LDA or acylation and further basic treatment.Similarly, 1-arylmethyl-4,6-diphenyl-2-dicyanomethylene-1,2-dihydropyridines by action of LDA undergo cyclization to the corresponding 2-amino-1-cyano-3-aryl indolizinies.
PREPARATION AND THERMAL BEHAVIOUR OF 1-SUBSTITUTED 2-DICYANOMETHYLENE-1,2-DIHYDROPYRIDINES: SYNTHESIS OF 2-PYRIDYL MALONITRILES.

1-Substituted 2-methylthio-4,6-diphenylpyridinium iodides (2) react with malonitrile under the influence of bases to give 1-substituted 1,2-dihydropyridines (3),which by thermal treatment can be converted into 2-pyridyl malonitriles (4).
