| abstract | 1476333 Urea and hydantoin derivatives PHILAGRO 21 May 1974 [22 May 1973] 22604/74 Heading C2C The invention comprises novel urea and hydantoin derivatives of the Formulµ I and II wherein R is a hydrogen atom or an alkyl, haloalkyl, cycloalkyl, carboxyalkyl optionally substituted aryl (except 3,5-dichlorophenyl), optionally substituted aralkyl, acyl, aroyl, or optionally substituted heterocyclic radical; R 1 is a hydrogen atom or C 1-5 alkyl radical; R 2 is a hydrogen atom, an alkyl radical optionally substituted by halogen or hydroxyl radicals, or a formyl, acyl, or mono- or di-N-C 1-4 alkyl substituted carbamoyl radical; R 3 is a carboxylic acid radical or an ester, amide or nitrile derivative or a salt thereof, the salt being of an alkali metal, alkaline-earth metal or heavy metal; and X is an oxygen or sulphur atom; or a salt thereof provided that when R 3 is a nitrile derivative then both R 1 and R 2 are hydrogen atoms. Compounds of the Formula I in which R 3 is a -COOH radical are made by reacting isocyanates or isothiocyanates R-N=C=X with methionine or its derivatives Compounds of the Formula I in which R 3 is a cyano group are obtained by reacting isocyanates or isothiocyanates R-N=C=X with 2- amino-4-methylthiobutyronitrile Compounds of the Formula II are obtained by cyclizing urea derivatives of the Formula I or, when R 2 is a hydrogen atom, by reacting amines R-NH 2 and isocyanates R 4 being a C 1-4 alkyl group. Compounds of the Formula II wherein R 2 is other than hydrogen may be obtained by reacting the corresponding 1-unsubstituted hydantoin derivatives with reactants R 2 -Z, Z being an inorganic anion, or with an isocyanate. Sulphonium salts of compounds of the Formula II may be obtained by reacting them with C 1-5 alkyl halides. A composition for regulating plant growth comprises as active ingredient a compound of Formula I or II above together with a carrier or diluent therefor. |
