The design of trisubstituted triazoles set the stage for proximity-induced iron-catalyzed C-H activation of benzyl and aryl amines with ample scope. Thereby, C-H alkylations and C-H arylations proved viable with high levels of chemo and positional selectivities by means of racemization-free iron catalysis with the reusable triazole being removed in a traceless fashion.

Succinate dehydrogenase inhibitors (SDHIs) are fungicides with an amide bond widely used to control plant diseases caused by phytopathogenic fungi. Because of broad spectrum activity of new SDHIs, they have attracted wide attention from the research community. A series of structurally novel SDHIs with a bioactive 1,2,3-triazole moiety were designed and synthesized. Bioactivity screening showed that some of designed N-phenethyl-1,2,3-trizole-4-carboxyl amide analogues exhibited good fungicidal activities toward Sclerotinia sclerotiorum and Botrytis cinerea, while some of Nbenzyl- 1,2,3-trizole-4-carboxyl amide analogues exhibited good fungicidal activities toward Phytophthora capsici and Cercospora arachidicola. EC50 value of compound 5d against Cercospora arachidicola (6.6 μg/mL) was lower than that of chlorothalonil (12.3 μg/mL).

Design, synthesis, and fungicidal evaluation of a series of novel 5-methyl-1H-1,2,3-trizole-4-carboxyl amide and ester analogues

Succinate dehydrogenase inhibitors (SDHIs) are efficient fungicides that are widely used to control plant diseases caused by phytopathogenic fungi, although their effectiveness is undermined by the development of resistance across a range of different fungi. One of the most common structural features of SDHIs is their amide bond. The introduction of greater structural diversity to SDHIs is a promising strategy to delay the onset of resistance. A series of novel SDHIs containing a bioactive 1,2,3-triazole moiety have been designed and synthesized and their fungicidal and insecticidal activities evaluated. The results of these analyses show that most of the newly synthesized 1,2,3-trizole-4-carboxyl amide (ester) analogues exhibit good fungicidal activities, especially towards Sclerotinia sclerotiorum, and a structure-activity relationship study confirmed that the replacement of the amide group with an ester group had little effect on fungicidal activity, which could be provideous in terms of issues and metabolism. 1,6-Dimethyl phenyl was confirmed as the most efficient substituent of the current study when it was placed on both the amide and ester compounds. Interestingly, some of the newly synthesized compounds displayed good insecticidal activities against Culex pipiens pallens. The results of the current study show that these 1,2,3-triazole-4-carboxyl amide and ester analogues represent a new type of SDHI that could be used for the development of novel pesticides.
Boronic acid catalysis for mild and selective [3+2] dipolar cycloadditions to unsaturated carboxylic acids
Zheng, Hongchao,McDonald, Robert,Hall, Dennis G.
experimental part, p. 5454 - 5460 (2010/09/15)
Herein, the concept of boronic acid catalysis (BAC) for the activation of unsaturated carboxylic acids is applied in several classic dipolar [3 + 2] cycloadditions involving azides, nitrile oxides, and nitrones as partners. These cycloadditions can be used to produce pharmaceutically interesting, small heterocyclic products, such as triazoles, isoxazoles, and isoxazolidines. These cycloadducts are formed directly and include a free carboxylic acid functionality that can be employed for fur-ther transformations, thereby avoiding prior masking or functionalization. In all cases, BAC provides faster reactions, under milder conditions, with much improved product yields and regioselectivities. In some instances, such as triazole formation from the reaction of azides with 2-alkynoic acids, catalysis with ort/io- nitrophenylboronic acid circumvents the undesirable product decarboxylation observed when using thermal activation. By using NMR spectroscopic studies, the boronic acid catalyst was shown to provide activation by a LUMO-lowering effect in the unsaturated carboxylic acid, likely via a monoacylated hemiboronic ester intermediate.
