4-羟基-6-甲基-2-吡喃酮(三乙酸内酯)在C-3与2-丁烯醛及类似的醛通过Michael加成反应。非孤立的中间体可以通过至少五种不同的方式进行转化。相反，标题吡喃酮与肉桂醛的反应发生在醛的羰基上。
4‐Hydroxy‐6‐methyl‐2‐pyrone (triacetic acid lactone) reacts at C‐3 with 2‐butenal and similar aldehydes by Michael addition. The nonisolated intermediates can undergo transformations in at least five different ways. On the contrary, reaction of the title pyrone with cinnamaldehyde occurs at the carbonyl group of the aldehyde.
