- PRODUCTION METHOD OF OPTICALLY ACTIVE SECONDARY ALCOHOL
-
PROBLEM TO BE SOLVED: To provide a chemical catalytic method allowing efficient production of a corresponding optically active secondary alcohol from an aromatic ketone having a substituent at each of two β-positions in an aromatic ring to the carbonyl site, so that both enantiomers can be separately made. SOLUTION: A production method of optically active secondary alcohol is characterized by reacting a ketone compound such as acetophenone derivatives with hydrogen in the presence of a ruthenium complex catalyst having an optically active diphosphine ligand.

- Synthesis of chiral nonracemic 4-trans-substituted pipecolic acid derivatives
-
The syntheses and resolutions of enantiomerically enriched 4-phenyl, 4- tert-butyl, and 4-isopropyl pipecolic acids are described. Optically active diastereomers were prepared by diastereomeric salt formation with the chiral base, L-tyrosine hydrazide, to

- Reactivity of perfluoro-(cis-2,3-dialkyloxaziridines) with heteroaromatic nitrogen compounds
-
Pyridine N-oxides 3 are exclusively formed under particularly mild conditions when perfluorinated dialkyloxaziridines 1 are reacted with pyridine derivatives 2 bearing a substituent at the 2-position. Starting from pyridines substituted at the 3- and 4-positions, the previously unreported N-perfluoroacylpyridiniumaminides 4 are also produced and isolated as solid, stable compounds. Bis(pyridinium-N-aminides) 9, which have been prepared starting from bis-pyridine substrates and pyridazine and quinoxaline starting materials, also show the same reactivity. This behaviour reveals how oxaziridines 1 can work as both animating and oxygenating agents.
