Heating of an equimolar mixture of 3,5-di-tert-butyl-1,2-benzoquinone with thiosalicylic acid led to 2-[(4,6-di-tert-butyl-2,3-dihydroxyphenyl)thio]benzoic acid. In the case of β-mercaptopropionic acid, 2-[(4,6-di-tert-butyl-2,3-dihydroxyphenyl)thio]propionic acid was formed, which upon reflux in Ac2O was converted to 6,8-di-tert-butyl-9-hydroxy-3,4-dihydro-2H-1,5benzoxathiepin-2-one.
加热 3,5-二叔丁基-1,2-苯醌与硫代水杨酸的等摩尔混合物生成 2-[(4,6-二叔丁基-2,3-二羟基苯基)硫代]苯甲酸. 对于 β-巯基丙酸,形成 2-[(4,6-二叔丁基-2,3-二羟基苯基)硫代]丙酸,在 Ac2O 中回流后转化为 6,8-二-叔丁基-9-羟基-3,4-二氢-2H-1,5benzoxathiepin-2-one。
