Inhibitory salt effect on the SNAr based macrocycloetherification of a linear diarylheptanoid

Salt effects exerted on the cycloetherification of linear diarylheptanoid 3-OH-4-MeOC6H3(CH2)2COCMe2CO(CH2)2C6H3-3-F-4-NO2 were investigated. Both salting-in and salting-out alkali salts were found to inhibit the macrocyclization. Ion-pairing exchange was proposed to account for the exptl. observations. [on SciFinder (R)]
