Front Cover: Ring‐Rearrangement Driven Formal (3 + 2) Cycloaddition of Enaminone‐Based Thioalkynes with Nitriles to Form Thiazole Containing Bis‐Heterocycles (Eur. J. Org. Chem. 31/2025)

The Front Cover depicts a synthetic route for pharmaceutically important bis-heterocyclic 3,4-dihydropyridin-2(H)-one containing thiazole derivatives by triflic acid-mediated ring rearrangement and formal (3 + 2) cycloaddition reaction of enaminone-based thioalkynes with nitriles. The outcome of reaction is decided by the substitution pattern on the cyclohexenyl ring. The developed protocol is operationally simple with a shorter reaction time and features a wider substrate scope delivering a very good to excellent yield of products.
