alcohol derivatives is described, in five steps from methyl 3,4-di(hydroxy)benzoate via a Newman–Kwart rearrangement. Incubation of these derivatives in formic acid affords 2,3,7,8,12,13-hexakis(alkylsulfanyl)-10,15-dihydro-5H-tribenzo[a,d,g]cyclononene products, which are hexa-sulfanyl analogues of the well-known supramolecular cavitand host, cyclotriveratrylene (CTV). The yield of this cyclization depends
描述了从3,4-二(羟基)苯甲酸甲酯通过Newman-Kwart重排的五个步骤中合成了四种3,4-二(烷基硫烷基)苄醇衍生物。这些衍生物在甲酸中孵育后得到2,3,7,8,12,13-六(烷基硫烷基)-10,15-二氢-5 H-三苯并[ a,d,g ]环壬烯产物,它们是六硫烷基著名的超分子空泡基质宿主的类似物,环三藜芦烯(CTV)。该环化的产率在很大程度上取决于存在的烷基硫烷基取代基,顺序为SMe> SEt≈S i Pr≫ SBn。对一种环三聚体的晶体结构测定显示出CTV本身通常表现出的自缔合模式。
