Organocatalytic Enantioselective Sulfenylation of β-Keto Phosphonates: A Convenient Approach to Construct Hetero-Quaternary Stereocenters was written by Lin, Aijun;Fang, Ling;Zhu, Xi;Zhu, Chengjian;Cheng, Yixiang. And the article was included in Advanced Synthesis & Catalysis in 2011.Reference of 14204-27-4 This article mentions the following:
The highly effective and enantioselective sulfenylation of β-keto phosphonates catalyzed by α,α-diaryl-
2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4) belongs to indole derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Reference of 14204-27-4
