Abstract
Thermal reaction of β-cellobiosyl fluoride heptaacetate with ticogenin in toluene or o-xylene at 112–142 °C gave ticogenyl β-cellobioside heptaacetate in 69–75% yields with good stereoselectivity. The procedure avoids the use of Lewis acid or traditional glycosidation promotors. The deacetylated product is a hypocholesterolemic and anti-atherosclerosis agent.
