Article abstract of DOI:10.1007/BF00513578

Acyl derivatives of the Fisher base react in the presence of phosphorus oxychloride with m-diethylaminophenol or resorcinol, forming spiro(indoline-2,2'-(2H)chromenes) and spiro(indoline-2,4'-(4H)chromenes.The ratio of the isomers depends on the solvent a
