## Abstract **Chiraler PTC**: Eine hoch effiziente asymmetrische Michael‐Addition von 3‐Aryloxindolen gelang mit einem Tetraalkylphosphoniumsalz als chiralem Phasentransferkatalysator (PTC). Die Produkte wurden in nahezu quantitativen Ausbeuten und mit hohen __ee__‐Werten erhalten. Derselbe Katalys
