Abstract

Several primary and secondary symmetrical diols, ranging from propane-1, 3-diol to decane- 1, 10-diol, are selectively monoprotected by monotetrahydropyranyl ether formation catalysed by a strongly acidic ion-exchange resin (Dowex 50w× 2, 50–100 mesh) in a 3, 4- dihydro-2H-pyran-hydrocarbon mixture.
