An investigation into the comparative reactivity of simple β-lactones and β-thiolactones toward a thiol and a primary amine is reported. A simple 3-mercaptomethyl-2-oxetanone is found to undergo rearrangement in the presence of aqueous base to give the corresponding thietane-3-carboxylic acid rather than the 3-hydroxymethyl-2-thietanone. Implications for the use of β-thiolactones in bioorganic and medicinal chemistry are discussed.
报告了对简单的β-内酯和β-硫内酯对硫醇和伯胺的比较反应性的研究。发现简单的3-巯甲基-2-氧杂环丁酮在碱性水溶液中会发生重排,生成相应的硫杂环丁烷-3-羧酸,而不是3-羟甲基-2-硫杂环丁酮。讨论了β-硫内酯在生物有机和药物化学中的应用。
