Aldol reactions of sugar aldehydes (5 – 13) with enolate 2 of racemic and both enantiomeric forms of acetyliron were investigated. The steric course of reactions depended strongly on the counterions used. High stereocontrol was achieved with the following cations: tin(II), diethylaluminum(I), zirconium(IV) and the triethylaluminum-containing cation. Matched pairs, particularly with the pentose- and
