SYNTHESIS OF PHLOROGLUCINOL TRIALKYL ETHERS
The alkylation of phloroglucinol dialkyl ethers with alcohols or alkyl halides leads, depending on the reaction conditions, either to products of O- or C- alkylation, or to C,O-alkylation products.Reaction conditions were found which enable us to obtain pure phloroglucinol trialkyl ethers.A convenient preparative method for the synthesis of phloroglucinol trialkyl ethers consists in the alkylation of phloroglucinol dialkyl ethers in a two-phase system in presence of phase-transfer catalysts.
