Solvent Free Three-Component Synthesis of 2,4,5-trisubstituted-1<i>H</i>-pyrrol-3-ol-type Compounds from <i>L</i>-tryptophan: DFT-B3LYP Calculations for the Reaction Mechanism and 3<i>H</i>-pyrrol-3-one↔1<i>H</i>-pyrrol-3-ol Tautomeric Equilibrium
In this paper, we describe the solvent-free three-component synthesis of 2,4,5-trisubstituted-1<i>H</i>-pyrrol-3-ol-type compounds from <i>L</i>-tryptophan. The first step of the synthetic methodology involved the esterification of <i>L</i>-tryptophan in excellent...
