  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Pyrazolo[3,4-d]thiazolo[3,2-a]pyrimidines were formed on halogenation of 5-allyl-6-thioxopyrazolo[3,4-d]-pyrimidin-4-one, whereas 5-ethylsulfanyl-2-halomethyl[1,3]oxazolo[3,2-c]pyrazolo[4,3-e]pyrimidinium tri-halogenides were formed from 5-allyl-6-ethylsulfanyl-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one.
