structures were prepared, in each case using the intramolecular cyclisation of a diyne as a key step. The complexes were generated as enantiomerically enriched through (i) asymmetric synthesis of a C2-symmetric diol following a reported protocol, (ii) resolution of enantiomerically-enriched diastereoisomers formed from a chiral alcohol and (iii) kinetic resolution of a racemic ketone-containing iron tricarbonyl

of enantiomerically-pure ruthenium tricarbonyl cyclopentadienonecomplexes were prepared via the cyclisation of C2-symmetric dialkynes with Ru3(CO)12. Four complexes were characterised by X-ray crystallography and a hydride derivative of one of these was characterised. The complexes were tested in the asymmetrichydrogenation and transfer hydrogenation of acetophenone. Whilst the catalysts were active

A systematic study of the asymmetric transfer hydrogenations of functionalized acetylenic ketones and diketones has been completed, together with a total synthesis of (S,S)-(-)-yashabushidiol B. In several cases, excellent enantioselectivities and yields were achieved.
