Metal-free intramolecular amino-acyloxylation of 2-aminostyrene with carboxylic acid for the synthesis of 3-acyloxyl indolines in water
A metal-free amino-acyloxylation of 2-aminostyrene was developed for the synthesis of 3-acyloxyl indolines. In the presence of N,N,N-trimethyldodecan-1-aminium iodide and TBHP, the reaction can be carried out in water smoothly with various carboxylic acids. And for internal alkenes, a stereoselective product was formed.
