In an article, author is Huang, Huabin,once mentioned of 110351-94-5, Safety of (S)-4-Ethyl-4-hydroxy-7,8-dihydro-1H-pyrano[3,4-f]indolizine-3,6,10(4H)-trione.
Base-Promoted Oxidative Dearomatization of Pyrroles to 4-Pyrrolin-2-ones
A base-promoted oxidative dearomatization of substituted pyrroles for the synthesis of 3,3-disubstituted 4-pyrrolin-2-ones under mild reaction conditions is described. A cascade aerobic oxidation/semipinacol rearrangement reaction was involved, and the desired products bearing a quaternary carbon center were efficiently prepared using molecular oxygen (O-2) as an ideal oxidant.
