p-thiomethoxymethyl derivative on reaction with N,N′-dicyclohexylcarbodiimide and dimethyl sulfoxide in a moderately acidic medium. Similar treatment of ortho-unsubstituted phenols affords small amounts of products containing the 5,6-benzo-1,3-oxathian ring system in addition to the normal products described in the preceding paper.1 Studies designed to elucidate the mechanisms of these transformations
在中度酸性介质中,与N,N'-二环己基碳二亚胺和二甲基亚砜反应后,将2,6-二甲基苯酚转化为其对硫代甲氧基甲基衍生物。除先前论文中所述的常规产品外,对邻-未取代的苯酚进行相似的处理也可得到少量的含有5,6-苯并-1,3-氧杂亚砜环系统的产品。1旨在阐明这些转化机制的研究与第二个oxathian环合成一起进行了描述。
