“…They are part of the combined preparations. Although other inhibitors of sterol synthesis outperform the group of morpholines by economic parameters, these substances again acquire importance for the problem of the resistance to fungicides [62]. In contrast to triazoles, morpholines block the isomerization and reduction reactions in the process of sterols biosynthesis, therefore the populations of fungi that are resistant to them are formed much more slowly.…”

The establishment of safe and effective methods for controlling fungal diseases is an urgent issue in agriculture and forestry. Fungicide research has provided a wide range of products with new modes of action. Extensive use of these compounds in agriculture enhances public anxiety due to the harmful potential for the environment and human health. Moreover, the phytotoxic effects of some fungicides are already recognized but still little is known about their influence on the photosynthetic apparatus and plant physiology. This review provides an understanding of the mechanisms of action of fungicides, mechanisms of fungicide resistance development, and the phenomenon of phytotoxicity.

“…In this study, two derivatives of morpholine were selected as cations. This water soluble amino ether is commonly applied in agrochemicals, biocides and fungicides, partly because of its surface active properties (Lamberth 2012 ). The formation of the ionic liquid structure may notably change the physicochemical properties of the original pesticide (Pernak et al 2015b ).…”

Comparative study on the biodegradability of morpholinium herbicidal ionic liquids

et al. 2015

This study focused on evaluating the toxicity as well as primary and ultimate biodegradability of morpholinium herbicidal ionic liquids (HILs), which incorporated MCPA, MCPP, 2,4-D or Dicamba anions. The studied HILs were also subjected to determination of surface active properties in order to assess their influence on toxicity and biodegradability. The study was carried out with microbiota isolated from different environmental niches: sediments from river channel, garden soil, drainage trench collecting agricultural runoff stream, agricultural soil and municipal waste repository. The obtained results revealed that resistance to toxicity and biodegradation efficiency of the microbiota increased in the following order: microbiota from the waste repository > microbiota from agricultural soil ≈ microbiota from an agricultural runoff stream > microbiota from garden soil > microbiota from the river sludge. It was observed that the toxicity of HILs increased with the hydrophobicity of the cation, however the influence of the anion was more notable. The highest toxicity was observed when MCPA was used as the anion (EC50 values ranging from 60 to 190 mg L−1). The results of ultimate biodegradation tests indicated that only HILs with 2,4-D as the anion were mineralized to some extent, with slightly higher values for HILs with the 4-decyl-4-ethylmorpholinium cation (10–31 %) compared to HILs with the 4,4-didecylmorpholinium cation (9–20 %). Overall, the cations were more susceptible (41–94 %) to primary biodegradation compared to anions (0–61 %). The obtained results suggested that the surface active properties of the studied HILs may influence their toxicity and biodegradability by bacteria in different environmental niches.

“…Tetrahydro-1,4-oxazines, namely morpholine derivatives, are privileged core skeletons that continually appear in numerous pharmaceuticals and agrochemicals. , It belongs to the top 25 most frequent N -heterocycles in US FDA approved drugs . Recently, trifluoromethylated morpholines have received substantial interest because the incorporation of a trifluoromethyl (CF 3 ) − group can significantly improve their physical, biological and chemical properties .…”

Electrochemical Intramolecular Oxytrifluoromethylation of N-Tethered Alkenyl Alcohols: Synthesis of Functionalized Morpholines

2020

View full text Add to dashboard Cite

An electrochemical intramolecular oxytrifluoromethylation of N-tethered alkenyl alcohols was developed providing straightforward access to CF3-containing morpholines derivatives. The method features mild reaction conditions with direct anodic oxidation of Langlois reagent as a cheap and easy to handle trifluoromethylating reagent. Variously substituted 2-(2,2,2-trifluoroethyl)morpholines were obtained in moderate to high yields under constant current electrolysis in an undivided cell.
