资源简介：
A series
of fused-bicyclic acetals containing a disiloxane ring
was investigated to evaluate the source of selectivity in silyl-protected
2-deoxyribose systems. The disiloxane ring unexpectedly enables the
diaxial conformer of the cation to be stabilized by an electronegative
atom at C-3. This low energy conformer subsequently undergoes stereoelectronically
controlled nucleophilic addition to give substituted tetrahydrofurans
with high diastereoselectivity.
