An Enantioselective Approach to 2,3-Disubstituted Indolines through Consecutive Brønsted Acid/Pd-Complex-Promoted Tandem Reactions
In tandem: A divergent and enantioselective approach to 2,3‐disubstituted indolines was developed through consecutive Brønsted acid/Pd‐complex‐promoted tandem reactions from simple 2‐substituted indoles and aldehydes in one operation to give up to 98 % ee (see scheme; R1=H, F, or Me; R2=alkyl; R3=ar...

Zusammenfassung: | In tandem: A divergent and enantioselective approach to 2,3‐disubstituted indolines was developed through consecutive Brønsted acid/Pd‐complex‐promoted tandem reactions from simple 2‐substituted indoles and aldehydes in one operation to give up to 98 % ee (see scheme; R1=H, F, or Me; R2=alkyl; R3=aryl or alkyl). Three Brønsted acid promoted steps and two Pd‐catalyzed hydrogenation steps were involved in this process. |
