Abstract :
An efficient method is described for the mild and rapid tetrahydropyranylation of alcohols and phenols using a catalytic amount of N-chlorosaccharin (1 mol %) and 3, 4-dihydro-2H-pyran under solvent-free condition at room temperature. Benzylic alcohols and phenols containing electron withdrawing or donating groups in various positions of phenyl ring, cinamyl alcohol, primary, secondary, tertiary as well as cyclic alcohols are converted to their corresponding tetrahydropyranyl ethers in short reaction times and in excellent yields via the present method. Primary benzylic alcohols in the presence of secondary ones and also primary or secondary aliphatic alcohols in the presence of tertiary ones can be efficiently tetrahydropyranylated with excellent selectivity via this method.
