Solvent free tetrahydropyranylation of alcohols and phenols over sulfuric acid adsorbed on silica gel
Alcohols and phenols are tetrahydropyranylated in the presence of sulfuric acid adsorbed on silica gel in high to excellent yields in solvent free conditions and is expedited by microwave irradiation. Addition of methanol performs the complete deprotection.
We present herein a micro reactor set-up that enables parallel syntheses to be performed under electroosmotic flow conditions. The Royal Society of Chemistry.
