    Abstract: PROBLEM TO BE SOLVED: To provide a new fluorescent intercalative dye or the like which shows a large fluorescent enhancement upon intercalation into a double-stranded nucleic acid when used in detection of the nucleic acid, shows a great difference between the excitation wavelength and the fluorescence wavelength (i.e., has a large Stokes shift). SOLUTION: The purpose is attained by providing a compound represented by general formula 1, particularly e.g. compound 1 represented by formula 1A or a salt, hydrate, solvate or stereoisomer thereof, a method for producing these compounds and a nucleic acid probe obtained by bringing these compounds into contact with a nucleic acid or a nucleic acid probe obtained by chemically bonding these compounds to a single-stranded oligonucleotide.

    Abstract: PROBLEM TO BE SOLVED: To obtain a new 3-aminothiophene derivative useful as a synthetic intermediate, etc., of various physiologically active substances such as a medicine, an agrochemical, etc. SOLUTION: This new 3-aminothiophene derivative is a compound of formula I [R1, R2 are H, F, nitro, a lower alkyl, a alkoxy, a lower alkoxycarbonyl or a lower acryl; R3 is a lower alkyl; R4 to R7 are each H or a lower alkyl), e.g. N-(2-hydroxyethyl)-N-methyl-3-aminothiophene. Further, the compound of the formula I is obtained by reacting a 3-halothiophene derivative of formula II (X is a halogen) with an aminoalcohol derivative of formula III in an inert organic solvent such as tetrahydrofuran in the presence of a base such as triethylamine.

    Abstract: PROBLEM TO BE SOLVED: To simply and economically produce the subject derivative, having a readily modifiable substituent group and useful as a production intermediate for physiologically active substances by reacting a phenol compound with a halogenothiocarbamating agent. SOLUTION: This compound is represented by formula I (R is a tri-lower alkylsilyl, a group represented by formula II (R1 is a lower alkoxy, cyano, a lower alkoxycarbonyl, etc.), etc.; V is a halogen), e.g. 4-(2-amino-1,1- dimethylethyl)phenoxy-tert-butyldimethylsilane. The objective derivative is preferably produced by reacting, e.g. a phenol compound represented by formula III with a halogenothiocarbamating agent, e.g. thiophosgene in the presence of a base in or without a solvent at -10 to +10 deg.C for several min to 24hr.

    Abstract: PURPOSE:To obtain a herbicide capable of controlling various weeds from the pre-sprouting stage to growing stage and having high safety to crops by using a sulfonamide derivative having oxadiazole ring and its salt as an active component. CONSTITUTION:The objective herbicide contains a compound of formula [X is alkyl, OH, alkoxy, NH2, NO2 or halogen; X is H or halogen; R is H, alkyl, COOR (R is alkyl), phenyl, benzyl, etc.; Y is H, alkyl, alkenyl, alkynyl, etc.) and its salt (e.g. salts produced by NaOH, ammonia, etc.] as an active component. The herbicide can be used in combination with other agricultural chemicals such as fungicide, insecticide, herbicide and plant growth regulator. Especially, the labor can be saved and the herbicidal spectrum is expected to be expanded by the mixed use with other herbicide. The rate of application is 10-500g of the active component per 10 are.
