By using an ammonium chloride salt as water solubilizing moiety, our oniumsaltsupported organic synthesis strategy was extended to water as a solvent. This method allows for high loading capacities both of the supports and their solutions owing to low molecular weight of the onium salts and simplified purification steps as well.
application of the use of task specific onium salts (TSOSs) as solublesupports in Grieco ’s multicomponent synthesis of tetrahydroquinolines. These solublesupports are of wide applicability and combine advantages of solid phase synthesis without its limitations with those of solution phase chemistry. After a simple washing step, products were cleaved from the supports and obtained in pure form and good yields
