1,2,3-triazolyl cyclohexanol derivatives have been disclosed and their use as ligands accelerating the copper(I)-catalyzed azide-alkyne cycloaddition and the zinc(II)-catalyzed azide-nitrile cycloaddition.

Acylhomoserine lactone (AHL) analogues in which the amide function is replaced by a triazole group were synthesized and evaluated for their effect on quorum sensing (QS) and biofilm formation in Burkholderia cenocepacia and Pseudomonas aeruginosa. In addition, the influence of the length of the acyl-mimicking chain was investigated. The compounds showed selectivity between two different AHL QS systems. 3-(1H-1,2,3-Triazol-1-yl)dihydrofuran-2(3H)-ones, in which the 4-substituent best resembled the acyl chain of the native AHL molecule exhibited significant QS agonistic and antagonistic activities. Replacing this aliphatic substituent by a phenyl-containing moiety resulted in active inhibitors of QS. The most active compounds showed biofilm inhibitory as well as biofilm eradicating activities in both test organisms. (C) 2012 Elsevier Ltd. All rights reserved.

Efficient procedures for the copper-catalyzedHuisgen cycloaddition reaction in aqueous media were developed using a novel water-soluble catalytic ligand, 2-4-[(dimethylamino)methyl]-1,2,3-triazol-1-yl}cyclohexan-1-ol (AMTC). A series of aliphatic and aromatic substrates were tested and compared to the well-known tris(triazole)amine ligands (TBTA and THPTA). The effect of solvent composition was also
