WebOct 1, 2024 · A simple one-pot approach was developed for the synthesis of furan-2(5H)-one derivative containing indole fragments. This method includes the telescoped multicomponent reaction of indole, 4-methoxyphenylglyoxal, and Meldrum’s acid. The synthetic utility of the prepared furan-2(5H)-one was demonstrated by condensation with … WebMay 15, 1980 · Introduction The detection and structural characterisation of phosphoranyl radical intermediates by ESR spectro- scopy has received much attention in recent years. Sucli radical species have generally been produced by radical or atom addition to tervalent phosphorus [1 3] or by electron addition to pentavalent phos- phorus [4 8] compounds ...
