In this study, 2,6‐trimethyl‐4H‐1,3‐dioxin‐4‐one compound, which is a source of Acetylketene, was reacted with terminal alkynes in presence of IPrAuCl (1,3‐Bis(2,6‐diisopropylphenyl‐imidazol‐2‐ylidene)gold(I) chloride) catalyst and a new synthesis method for 2‐methyl‐pyran‐4‐one compounds has been developed. It was observed that the yields were very low when this reaction was carried out without using a catalyst. However, 95 % yield was obtained when this reaction was performed in the presence of a IPrAuCl catalyst
