Abstract

Interaction of potassium salts of quinazolin-2-thiol-4-one with γ-substituted allyl halides gave thiazoloquinazolinones with linear or angular structures depending on the structure of the carbonyl radical. S-Allyl substituted quinazolin-2-thiol-4-one reacted with halogens to give iminium salts of thiazinoquinazolinone with an angular structure. The conversion of these salts to the corresponding
bases and thiazoloquinazolinones has been studied.
