    Abstract: PROBLEM TO BE SOLVED: To obtain a new nucleic acid probe having a base sequence complementary to a specific nucleic acid sequence, comprising a single-stranded nucleic acid labeled so as to exhibit a measurable fluorescence signal when bound to a nucleic acid having the nucleic acid sequence and useful for analysis of existence and amount of a specific nucleic acid or the like. SOLUTION: There is described a new nucleic acid probe having a base sequence complementary to a specific nucleic acid sequence, comprising a single- stranded nucleic acid labeled so as to exhibit a measurable luminescence signal when bound to a nucleic acid having the nucleic acid sequence and having 3'-terminal end modified as shown by the formula R is COOH, CONH2, (CH2)nOH (n is one or more integer), CH(OH)-CH2OH, CH(CH2)n-NHR1] (R1 is a protective group for amino group, a coloring material or H)}. The probe is used for a method for analyzing existence or amount of a target nucleic acid such as DNA or RNA having a specific nucleic acid sequence or the like, utilization in a field of clinical diagnosis such as gene diagnosis, search of an unknown gene.

    Abstract: PROBLEM TO BE SOLVED: To obtain a 3-aminothiophene derivative useful as a synthetic intermediate of a medicine, an agrochemical, etc., by reacting each specific thienyl halide derivative with an amine derivative in the presence of a copper catalyst, simply at a low cost in a high purity and in a high yield. SOLUTION: This new 3-aminothiophene derivative expressed by formula III is obtained by reacting a 3-thienyl halide derivative expressed by formula I (R1, R2 are each H, F, a lower alkyl, a lower alkoxy, a lower alkoxycarbonyl or a lower acyl; X is a halogen) with an amine derivative expressed by formula II (R3 is H or a lower alkyl; R4 is H, a lower alkyl or a lower alkyl substituted with hydroxyl) in the presence of a copper catalyst (amount of use is preferably 0.001-1 equivalent based on the derivative of formula I) consisting of a single substance or a mixture of two or more kinds selected from a metallic copper powder, metallic copper granules, a metallic copper wire, cuprous (I) oxide, cuprous (I) chloride, cuprous (I) bromide and cuprous (I) iodide, under a pressure of normal pressure to 1 MPa.

    Abstract: PURPOSE:To provide a new compound applicable without causing environmental problem and useful as a fungicide, especially an agricultural and horticultural fungicide free from the development of resistant fungi. CONSTITUTION:The compound of formula I (R is 1-5C alkyl, 2-5C alkenyl or 2-5C alkynyl; R to R are H, 1-10C alkyl, 2-10C alkenyl or 2-10C alkynyl; R is H, 1-10C alkyl, 2-10C alkenyl, 2-10C alkynyl, etc.), e.g. 2-methyl-3-(4- trimethylsilylphenyl)-1,2,3,4-tetrahydroisoquinoline. The compound of formula I can be produced by reacting a lactam derivative of formula II with a hydrogenation agent (e.g. lithium aluminum hydride) in a solvent (e.g. THF) at -10 to +200 deg.C. The amount of the hydrogenation agent is 0.2-20mol-equivalent based on 1mol-equivalent of the compound of formula II. The compound has excellent fungicidal activity against plant pathogens of powdery mildew of wheat, rust of wheat, powdery mildew of cucumber, etc.
