2- and 2,3-Substituted pyrroles are readily synthesized in a one-pot procedure from ketones, hydroxylamine hydrochloride, and 1,2-dichloroethane in the KOH/DMSO system (120 °C, 2–4 h), the yields of pyrroles ranging 11–85%. Aliphatic, cycloaliphatic, aromatic, and heteroaromatic ketones tolerate the reaction conditions.
在KOH / DMSO系统中(120°C,2-4 h),可通过酮,盐酸羟胺和1,2-二氯乙烷的一锅法轻松合成2-和2,3-取代的吡咯。吡咯含量为11–85%。脂族,脂环族,芳族和杂芳族酮可耐受反应条件。
