摘要:The compounds of the formula I (I) in which A denotes N or N->O, Z denotes O or NH, R denotes H, (halo)alkyl, (halo)alkenyl, (halo)alkynyl or alkoxycarbonyl, R1 denotes hydrogen, halogen, amino, -NHOH, hydroxyl, (substituted) phenylazo or a radical of the formulae Y=C=N-, Y1Y2C=N-, Y3NH- or K denotes 0 or 1, and m and n, independently of one another, denote a number from 1 to 4, with the proviso that, when Z-R denotes OH or NH2, (R1)n denotes at least one radical of the formula or represents two radicals, in the 5 or 6 position of the heterocyclic ring, which, in the 5 position, denote halogen and, in the 6 position, denote a radical of the group comprising halogen, amino, hydroxyl or phenylazo, which may be substituted as specified above, are valuable intermediates in the synthesis of plant protection agents.

摘要:Embodiments of the invention provide methods and materials for chemical cross-coupling reactions that utilize aryl alcohol derivatives as cross-coupling partners. Embodiments of the invention include methods for the amination of aryl sulfamates and carbamates, which are attractive cross-coupling partners, particularly for use in multistep synthesis. Illustrative embodiments include versatile means to use simple derivatives of phenol as precursors to polysubstituted aryl amines, as exemplified by a concise synthesis of the antibacterial drug linezolid.
