概要

• 論文の詳細を見る

• Optically pure 2,6-dimethyl-3,5-heptanediol (<B>1</B>), a new chiral auxiliary, has been prepared by the enantiodifferentiating hydrogenation of 2,6-dimethyl-3,5-heptanedione over tartaric acid–NaBr–modified Raney nickel catalyst (TA–NaBr–MRNi), and the preferential recrystallization of the hydrogenation product. Absolute configuration of <B>1</B> was determined to be 3<I>S</I>, 5<I>S</I> by the chemical correlation with (−)-ethyl (<I>S</I>)-3-hydroxy-4-methylpentanoate.
