A readily available and inexpensive natural alpha -amino acid is converted into a compound represented by formula (1), which is then reacted with an organometallic reagent represented by formula (2) to give an optically active 5-hydroxyoxazolidine represented by formula (3), which is then treated with an acid to provide an optically active aminoketone represented by formula (4). The product is then converted into an optically active aminoalcohol represented by formula (5) or (6) by, for example reduction.The above process can provide an optically active aminoalcohol represented by formula (5) or (6) useful as a production intermediate for a medicine or pesticide from a readily available and inexpensive natural alpha-amino acid as a starting material stereoselectively and stably with a higher optical purity and a lower cost without racemization. This invention can also provide an optically active 5-hydroxyoxazolidine represented by formula (3) and an aminoketone represented by formula (4) as important intermediates for production of the above product as well as preparation processes therefor.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 14305-08-9, name is 4,5-Dibromo-2-phenylpyridazin-3(2H)-one, introducing its new discovery. category: pyridazine

Six novel photochromic bisarylpyridazinones containing 2,5-dimethylthiophene or 5-methyl-2-phenylthiazole unit were synthesized, and their photochromic and fluorescence properties were investigated. The bisarylpyridazinones underwent reversible color change upon irradiation with UV or visible light. The effect of solvents on the absorption spectra of the bisarylpyridazinones was investigated. The closed-ring forms of bisarylpyridazinones displayed negative solvatochromism which was attributed to the high dipolar characters of the molecule. The open-ring forms of bisarylpyridazinones showed fluorescence at 400-480 nm upon excitation at 302 nm, and the intensities of emission bands gradually decreased during the ring-closing photoreactions. Among the synthesized bisarylpyridazinones, 4,5-bis(5-methyl-2-phenylthiazol-4-yl)-2-methyl(or 2-phenyl) pyridazin-3(2H)-ones (5O and 6O) displayed rather large absorption and emission spectral change, higher quantum efficiency during the photoreaction compared to others. A high conversion ratio (94%) to the closed form was observed for 5O.
