“…Although the mechanistic details of the reaction between pyrazolones 3 and carbon disul de in the presence of ECH are unknown, a possible explanation is proposed in Scheme 4. Initially, tautomeric intermediates I and II are generated from the reaction between pyrazolones 3 and carbon disul de in the presence of triethylamine [27,28]. Subsequently, the sulfur anion of I or II is added to ECH to generate intermediate III.…”

This study presents an effective one-pot strategy for the synthesis of hydroxylated 1,3-dithianepyrazolone hybrids. The process involves a reaction between pyrazolone derivatives and carbon disul de in the presence of epichlorohydrin (ECH). The structural elucidation of the products was accomplished using various spectroscopic techniques. To further corroborate the proposed reaction mechanism, enantiomerically pure ECH was utilized.
