A new two-step procedure for the synthesis of 1,4-dicarbonyls has been developed involving an efficient and clean Mo-catalyzed oxidativecleavage of cyclobutane-1,2-diols with DMSO, which is used as solvent and oxidant. The required starting glycols were prepared by nucleophilic additions of organolithiums and Grignard reagents to easily available 2-hydroxycyclobutanones.
已经开发了一种用于合成 1,4-二羰基化合物的新两步法,涉及使用用作溶剂和氧化剂的 DMSO 对环丁烷-1,2-二醇进行有效且清洁的 Mo 催化氧化裂解。所需的起始乙二醇是通过有机锂和格氏试剂对容易获得的 2-羟基环丁酮进行亲核加成而制备的。
