Many azolinethiones show reactions typical of thioamides in particular, they react with electrophiles at the sulfur atom. 

In another approach, the A((l)-y-hydroxypropyl isomer of (439) was cyclized in methanesulfonic acid <79CPB880>. Compounds (360)-(362) were formed (via the A -l-acylated intermediates) in high yields, as the only products in the reactions between the appropriate stereoisomeric quin-azolinethiones and acetylenedicarboxylate <89MRC959>.
