Synthesis of 1,3-diaryl-spiro[azetidine-2,3′-indoline]-2′,4-diones via the Staudinger reaction: cis- or trans-diastereoselectivity with different addition modes
A new synthetic approach for realizing biologically relevant bis-aryl spiro[azetidine-2,3′-indoline]-2′,4-diones was developed based on Staudinger ketene–imine cycloaddition through the one-pot reaction of substituted acetic acids and Schiff bases in the presence of oxalyl chloride and an organic ba...
