Reductive lithiation of 2-O-trimethylsilyl derivatives of phenyl thiogluco and -galactopyranosides gives rise to a 13 O→Csilyl migration leading to α-D-gluco and -galctopyranosyltrimethylsilanes in good yields. The expected β-elimination is observed to a small extent in the case of a 23-di-O-trimethylsilyl derivative of phenyl thioglucopyranoside where a tandem 13 O→C 14 O→O silylrearrangement occurs
