Fl. Vandelft et al., EFFICIENT ROUTE TO HIGHLY FUNCTIONALIZED TETRAHYDROFURANS BY STEREOCONTROLLED SILICON-DIRECTED CYCLIZATION, Recueil des travaux chimiques des Pays-Bas, 113(6), 1994, pp. 339-341
Cyclization of lsilyl-l-deoxy-1-phenyldiisopropylsilyl-L-glucitol in t
he presence of BF3.Et2O or catalytic H2SO4 proceeds stereoselectively
to give predominantly the fully benzylated 2,5-anhydro-L-glucitol deri
vative without occurrence of the Peterson elimination.
