Synthesis of series of 1- and 3-differently substituted xanthines from imidazoles.
A new and general method is described for the synthesis, in three steps and in good overall yields, of tetrasubstituted xanthines from an easily prepared imidazole precursor. The method is especially useful for the preparation in standardized conditions of series of xanthines combining a broad variety of primary or secondary alkyl, benzyl or aryl groups at N1 and of alkyl or arylmethyl groups a...

The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.

Twenty-eight 1-ethyland l-p ropyl-5-substitu ted imidazoles were synthesized and their bleaching activity was evaluated by using the lettuce seedling test. 5-Phenyl1-propylimidazole (1) caused distinct chlorosis, while none o f the com pounds with various alkenyl groups at the 5-position o f the im idazole ring showed this bleaching activity. In troduction o f a brom o, chloro, fluoro, methyl o...
