the 1H-1,2-benzodiazepines (7) having an electron-donating substituent in the 7-position with ethyl chloroformate, acetyl chloride, or benzoyl chloride in benzene results in ring-conversion to give the corresponding 1,3-diazepines (3) and (12).
用苯甲酸氯甲酸酯,乙酰氯或苯甲酰氯处理在7位具有给电子取代基的1 H -1,2-噻吩二氮杂(1)和1 H -1,2-苯并二氮杂(7)导致环转化,得到相应的1,3-二氮杂((3)和(12)。
