摘要

The ester-mediated nucleophilic aromatic substitution (SAr) reaction of 2-methoxybenzoic ester 1 with Grignard reagents 11 is greatly accelerated by introduction of a methoxy or halo substituent at the 3-position of the benzoate ring (7–10). The substituent effects of these groups at the 3-position are compared wit
