2-HYDROXY-1-ARYL-2-(INDOL-3’-YL)ETHANONES:SYNTHESIS, SPECTRAL CHARACTERISTICS, STRUCTURE
AND THEIR REARRANGEMENT INTO 2-HYDROXY-2-ARYL-1-(INDOL-3’-YL)ETHANONESVasiliy G. Shtamburg,Victor V. Shtamburg,Andrey A. Anishchenko,Alexander V.Mazepa,Svetlana V. Kravchenko, Svetlana V. Shishkina. Abstract | | | | A convenient method of synthesis of 2-hydroxy-1-aryl-2-(indol-3-yl)ethanones and their isomerization to 2-hydroxy-2-aryl-1-(indol-3-
yl)ethanones in the presence of triethylamine on heating or in the presence of EtONa at room temperature have been studied. The spectral
tests of isomers structures are presented. The structures of 2-hydroxy-1-phenyl-2-(indol-3-yl)ethanone and 2-hydroxy-2-phenyl-1-(indol-3-
yl)ethanone have been studied by XRD technique.
