An efficient one-pot procedure is described in which an isocyanate intermediate, generated from the corresponding carboxylic acid by a modified Curtius rearrangement, is captured by a tethered aromatic ring in the presence of BF3˙OEt2 to generate various lactams, including tetrahydro-β-carbolin-1-one and dihydroisoquinolin-1-one derivatives. cyclizations - heterocycles - lactams - Lewis acids - rearrangements
描述了一种有效的一锅法,其中在BF 3 = OEt 2存在下,由束缚的芳环捕获由相应的羧酸通过修饰的Curtius重排生成的异氰酸酯中间体,从而生成各种内酰胺,包括四氢- β-咔啉-1-酮和二氢异喹啉-1-酮衍生物。 环化-杂环-内酰胺-路易斯酸-重排
