2-Acyl-1,3-dithianes undergo efficient Lewis acid-catalysed addition to α,β-unsaturated ketones giving δ-diketones which suffer intramolecular aldol reaction to produce cyclohex-2-en-1,4-dione monoacetals and/or cyclohex-3-en-1,2-dione monoacetals.
2-酰基-1,3-二硫杂环丁烷经过高效路易斯酸催化的α,β-不饱和酮加成反应,生成δ-二酮,这些二酮经分子内羟醛反应生成环己-2-烯-1,4-二酮单缩醛和/或环己-3-en-1,2-二酮单缩醛。
