    摘要: This invention provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner through the implementation of vinylation of an amino-containing nucleic acid with a vinylating agent. This invention also provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner by a method in which PCR is carried out in the presence of an amino-modified nucleotide and dNTP and a vinyl group is introduced into the resulting PCR amplification product or by a method in which PCR is carried out in the presence of a vinyl-modified nucleotide and cNTP.

    摘要: The present invention provides a process for efficiently producing an optically active α-amino acid and an optically active α-amino acid amide. After contacting with cells or processed cells thereof having an ability to asymmetrically hydrolyse, a water solvent is substituted with at least one solvent selected from the group consisting of linear, branched, or cyclic alcohol having 3 or more carbon atoms and the optically active α-amino acid is preferentially precipitated from the alcohol solution.The addition of basic compounds, particularly potassium compounds to the alcohol solution containing the optically active α-amino acid amide, which is obtained after the separation of the optically active α-amino acid, enables the purification of the amide without the inclusion of amino acid into amino acid amide. Thus, the amide is subjected to the step of racemization and then recycled.

    摘要: The present invention relates to an optically active .alpha.-substituted carboxylic acid derivative represented by the general formula (I): ##STR1## (wherein R.sub.1 is a hydroxyl group, ##STR2## R.sub.2 is a methyl group or a chlorine atom; R.sub.3 is a hydrogen atom or an alkyl group with 1-6 carbon atoms; n is an integer of 1 or 2; and * represents an asymmetric carbon atom, provided that R.sub.2 is a chlorine atom when R.sub.1 is a hydroxyl group); and a method for producing the optically active .alpha.-substituted carboxylic acid derivative represented by the general formula (I) and antipodes thereof using a culture, cells or a material obtainable from cells of a microorganism having an ability to asymmetrically hydrolyze ester bonds. The optically active .alpha.-substituted carboxylic acid derivatives and antipodes thereof provided by the invention are useful as raw materials for various liquid crystals and as synthetic intermediates for various optically active medicines or agricultural chemicals.
