Synthesis of 2-halo-6-hydroxy-5,5-dimethyl(ethyl)-5,6-dihydro-1H-pyridine-3,4,4-tricarbonitriles by the reaction of tetracyanoethylene with aldehydes
摘要:
The reaction of tetracyanoethylene and isobutyraldehyde or 2-ethylbutanal in an excess of a hydrohalogen acid yields 2-halo-6-hydroxy-5,5-dimethyl(ethyl)-5,6-dihydro-3,4,4(1H)-pyridinetricarbonitriles, the crystal and molecular structures of which were characterised by IR, NMR, MS and X-ray analysis.

5,5-Dialkyl-2-halo-6-hydroxy-5,6-dihydro-1H-pyridine-3,4,4-tricarbonitriles reacted with morpholine in aprotic solvent to give the corresponding 3,3-dialkyl-4,5-dicyano-6-halo-2-morpholino-1,2,3,4-tetrahydropyridine-4-carboxamides, while analogous reaction in amphiprotic solvent resulted in the formation of 8,8-dialkyl-3-halo-6-oxo-2,7-diazabicyclo[3.2.1]oct-3-ene-4,5-dicarbonitriles.
