The Chemistry of an Azomethine Imine Derived From 2,3-Dimethylindole and N-Phenyl Triazolinedione: A New and Facile Condensation Method
The urazole 3 derived from 2,3-dimethylindole and PTAD has been found to be converted redily to the unusually stabel azomethine imine 5 with t-butlyhypochlorite followed by elimination of HCl. This azomethine imine has been shown to serve as a carbonyl-equivalent in a number of aldol-type condensations under mild conditions.
