Abstract

Reaction of active methylene compound with an aldehyde and thiourea under Biginelli conditions reported to yield dihydropyrimidine derivatives in good yield. Herein we report a special case wherein the isolated product was propanenitrile derivative resulting from Knoevenagel condensation of malononitrile with the aldehyde. The structure of the product was confirmed by single crystal X-ray diffraction studies.
