C-bifunctional sila- and germacyclopentanes have some potential as bio
logically active drugs. Ten representative 1-sila (and 1-germa) cyclop
entane-2,3 and 3,4-diols, cis or trans, were synthesized from the corr
esponding 1-metallacyclopen-3-enes. The influence of the metal, silico
n or germanium, on each step leading to 3 sets of alpha-diols is under
lined. The stereochemistry of the alpha-diols and their precursors was
established by H-1 and C-13 NMR spectroscopy.
