Maljutenko, Karolin,Borovkov, Victor,Kananovich, Dzmitry,J?rving, Ivar,Lopp, Margus

, p. 661 - 664 (2018)

A method for the aerobic cascade oxidation of cyclopentane-1,2-diones using metal porphyrins as catalysts, yielding hydroxydiacids 2, ketoacid 3 and diketoacids 4 which are the intermediates of important biologically active compounds is reported. This method is operationally simple and can be employed under ambient conditions.
