Abstract
Reported herein is a design and synthesis of N‐tert‐butylsulfinyl‐(perfluoro)benzaldimine, and a study of its reactivity and stereocontrolling properties in Mannich addition reactions with indolinone derived tertiary enolates generated in situ. The corresponding products, quaternary β‐perfluorophenyl‐β‐amino‐indolin‐2‐ones, were obtained with good to excellent yields and diastereoselectivity, underscoring the exciting synthetic potential of this newly introduced pentafluorophenyl‐containing chiral imine.
