A series of 4-amino-functionalized spiropyrimidine-2-thione derivatives were simply produced by the one-pot three-component reaction of alicyclic carbonylcompounds, nitriles containing an acidic methylene, and thiourea in the presence of NaOMe in MeOH.
for the synthesis of spiro-5-cyanopyrimidines by multi-component condensation of cyclic ketones, malononitrile and urea/thiourea using potassium carbonate in aqueous medium. The simple work-up procedure and good yield in short time are important features of this protocol. The synthesized compounds were tested for antibacterial activity against Gram positive and Gram negative bacteria and some of the
