utilization of the thiomethyl group to activate an aromatic ring system for closure to form the corresponding conformationally restrained 8-methoxy-7-(methylthio)-3-methyl-1-(spiro-1′-indan)2,3,4,5-tetrahydro-1H-3-benzazepine is described. Subsequent removal of the thiomethyl group with Raney nickel followed by electrophilic substitution allows for the synthesis of other benzazepines that have electron
利用硫代甲基活化芳香环系统以形成相应的构象受限的8-甲氧基-7-(甲硫基)-3-甲基-1-(螺-1'-茚满)2,3,4,描述了5-四氢-1H-3-苯并ze庚因。随后用阮内镍除去硫代甲基,然后进行亲电取代,可以合成具有通常不易获得的吸电子基团的其他苯并normally庚因。
