An improved one-pot synthesis of 1,5-benzothiazepinone derivatives is described. 2-Aminobenzenethiols are conveniently converted into 2,3-dihydro-1,5-benzothiazepin-4(5H)-ones by reaction with ß-propiol-actone or ß-butyrolactone in anhydrous pyridine followed by treatment with acetic anhydride. Some substituent effects are noted.
本文介绍了一种改进的 1,5-苯并硫氮杂卓酮衍生物的一步法合成方法。通过在无水吡啶中与ß-丙二醇内酯或ß-丁内酯反应,然后用乙酸酐处理,可方便地将 2-氨基苯硫酚转化为 2,3-二氢-1,5-苯并硫氮杂卓-4(5H)-酮。注意到了一些取代基的影响。
