The present study describes the Bi (III) chloride catalyzed transformation of 4'-hydroxy-3',5'-dinitrochalcones
into the corresponding benzoxazepines followed by sequential Michael addition using Bi (III) oxychloride as a procatalyst
efficiently.
本研究介绍了以 Bi (III) 氧
氯化物为催化剂,高效催化 4'-hydroxy-3',5'-dinitrochalcones 转化为相应的苯并氧氮杂卓,然后进行迈克尔顺序加成。
