Nitration of 3-acylindoles in the presence of MeCN solvates of Cu2+, Al3+, and Fe2+ salts yielded 3-nitroindole, 4-nitro-and 6-nitro-3-acylindoles, of which 3-acetyl-4-nitroindole was subsequently transformed into dehydrochuangxinmycin (7), the dehydro derivative of the antibiotic alkaloid chuangxinmycin (2).
在 Cu2+、Al3+ 和 Fe2+ 盐的 MeCN 溶剂存在下硝化 3-酰基吲哚,可得到 3-硝基吲哚、4-硝基和 6-硝基-3-酰基吲哚,其中 3-乙酰基-4-硝基吲哚随后转化为脱氢川霉素(7),即抗生素生物碱川霉素(2)的脱氢衍生物。
