Acid-catalyzed rearrangement of O-(2-arylpheynl) hydroxylamines followed by ring enlargement afford 7-aryl-2, 3-dihydro-1H-azepin-2-ones. 2-Amino-2-phenyl-3, 5-cyclohexadienone, an intermediate of the reaction, was trapped as the N-trifluoroacetamide.
O-(2-芳基苯炔基)羟胺的酸催化重排,然后扩环,得到7-芳基-2,3-二氢-1H-氮杂-2-基。反应的中间体2-氨基-2-苯基-3,5-环己二酮被捕集为N-三氟乙酰胺。
