    摘要： PURPOSE:To separate various compounds under nearly neutral state in high efficiency by liquid chromatography using a mobile phase consisting of a liquid produced by adding various salts to a mixture of water and a water-soluble organic solvent. CONSTITUTION:Liquid chromatography is carried out by using a separation agent containing a polysaccharide derivative (cellulose trisphenyl carbamate is most effective) produced by substituting a part or total (preferably >=85%) of hydrogen atoms on the hydroxyl groups of a polysaccharide with other atomic groups. In the above process, a liquid produced by adding various salts to a mixture of water and a water-soluble organic solvent (e.g. acetonitrile, methanol or ethanol) in a ratio of 100:0 to 0:100 is used as the mobile phase. The salt is preferably the one having strong chaotropic nature, e.g. perchlorate, thiocyanate, nitrate, iodide, perfluoroalkanoate, guanidium salt, quaternary ammonium salt, etc.

    摘要： PURPOSE:To produce the title compound which is useful as an analgesic or anticonvulsant such as scopolamine in high productivity, by culturing a line which can produce tropane alkaloid in high yield, selected from adventitious roots originating from haploid tissues in Solanaceae plants. CONSTITUTION:A haploid tissue (stamen or pistil) of Solanaceae plant such as a plant in Hyoscyamus is redifferentiated to form adventitious roots. Then, a line of high tropane alkaloid productivity is selected from the adventitious roots, cultured in a medium to produce the subject compound.

    摘要： NEW MATERIAL:A compound shown by the formula I (R is lower alkyl; A is tertiary amino-containing organic group).
    EXAMPLE: N-Methacryloylcarbamic acid dimethylaminoethyl ester.
    USE: Useful as a raw material for organic syntheses or for producing high-molecular polymer.
    PREPARATION: An isocyanate shown by the formula II is reacted with a hydroxyl compound (e.g., dimethylaminoethyl ethanol) shown by the formula A-OH in an inert solvent such as chloroform, hexane, toluene, at ≤100°C, preferably at room temperature under cooling with ice to give a compound shown by the formula I.
