Described herein is a novel base-promoted [4 + 2] annulation reaction of 3-methyl-indolin-2-ones with ortho-haloacetophenones, which enables the modular and reliable synthesis 2,3-fused indolines bearing quaternary carbon. Two C-C bonds can be successively constructed through tandem sequence involving SNAr aldol condensation. This protocol highlighted by transition metal-free conditions, high efficiency, simple operation.
