carbohydrate has been identified as an environmentally benign C2 synthon in the preparation of synthetically useful 2-hydroxymethylbenzimidazole derivatives by coupling with 1,2-phenylenediamines. The pivotal features of this method include metal-free conditions, short time, good functional group tolerance, gram scale feasibility and the synthesis of benzimidazole fused 1,4-oxazine.
D-果糖是一种生物质衍生的碳水化合物,在通过与 1,2-苯二胺偶联制备合成有用的 2-羟甲基苯并咪唑衍生物时,已将其鉴定为环境无害的 C 2合成子。该方法的关键特征包括无金属条件、时间短、官能团耐受性好、克级可行性和苯并咪唑稠合 1,4-恶嗪的合成。
