1,3-Diketones were reduced to 1,3-diols by using RuCl[N-(tosyl)-1,2-(diphenylethylenediamine) (h 6 -arene)] in the presence of formic acid and triethylamine. 1,3-Diols were obtained in good chemical yields and with high ee when symmetrical diketones were reduced.

The enantioselective ruthenium promoted hydrogenation of beta-keto ester, derived from (S)- or (R)-proline and (S)-pipecolic acid, provided a new efficient route to hydroxylated pyrrolizidine or indolizidine ring systems in diastereomeric excesses up to 99%. A practical synthesis of (+)-alpha-conhyd
