Alcoholysis, hydrolysis, and acetolysis of epoxides were carried out in the presence of a catalytic amount of aniline-terephthalaldehyde resin p-toluenesulfonate (ATRT) to give the corresponding β-substituted alcohols in good yields. Alcoholysis and hydrolysis of epoxides catalyzed by ATRT proceeded faster than those by pyridinium p-toluenesulfonate (PPTS).

Epoxides undergo rapid ring opening with a range of alcohols in the presence of catalytic amount of carbon tetrabromide under mild and convenient conditions to afford the corresponding β-alkoxy alcohols and 1,2-diols in high yields with high regioselectivity. Georg Thieme Verlag Stuttgart.

Ytterbium(III)triflate-catalysed ring-opening reactions of epoxides derived from styrene, cyclohexene, norbornene and stilbene, in the presence of alcohols (C1-C4 1°, 2° and 3° aliphatic alcohols, cyclohexyl alcohol, allyl and propargyl alcohol) resulted in the formation of β-alkoxy alcohols in good to excellent yield with high regio-, and, where applicable, stereoselectivity. Reaction of stilbene oxide with methanol in the presence of the diethyl ester of L-(+)-tartaric acid afforded the threo form of 1,2-diphenyl-2-methoxy ethanol with high diastereoselectivity (de 94%). Mechanistic implications of the results are discussed.
