抄録

The aldol reaction of tricarbonyl(o-trimethylsilyl(TMS)-benzaldehyde)chromium(0) complex (1a) with cyclic ketene silyl acetals (2-4) afforded the corresponding erythro products selectively. Changing the ortho TMS group to a triisopropylsilyl (TIPS) group in the complex brought about an improvement of the erythro selectivity in the case of the five-membered acetal (4).
