N-(benzyloxy)-2-chloronicotinamide compound as well as preparation method and application thereof

The invention belongs to the technical field of chemical synthesis and medicine application, and particularly relates to preparation and application of an N-(benzyloxy)-2-chloronicotinamide compound. The preparation method comprises the following steps: reacting phthalic anhydride with hydroxylamine, then reacting with triethylamine for acidification to prepare N-hydroxyphthalimide, then carrying out substitution and hydrazinolysis, and finally reacting with dichloronicotinoyl chloride to prepare the N-(benzyloxy)-2-chloronicotinamide compound. The preparation method disclosed by the invention is simple and convenient to operate, the structure of the obtained product is confirmed by a nuclear magnetic hydrogen spectrum, herbicidal activity tests are carried out on the obtained 15 target products, and results show that all target compounds have an obvious inhibition effect on the seeds of the Agrostis matsumurae under the concentration of 1mM, and the inhibition effect reaches 100%; and along with the decrease of the concentration, even if the concentration reaches 100 [mu] M, the target compound can still show good herbicidal activity.

Synthesis, Crystal Structure, Herbicidal Activity, and SAR Study of Novel N-(Arylmethoxy)-2-chloronicotinamides Derived from Nicotinic Acid

Nicotinic acid, also known as niacin, is a natural product, which is widely found in plants and animals. To discover novel natural-product-based herbicides, a series of N-(arylmethoxy)-2-chloronicotinamides were designed and synthesized. Some of the new N-(arylmethoxy)-2-chloronicotinamides exhibited excellent herbicidal activity against Agrostis stolonifera (bentgrass) at 100 μM. Compound 5f (2-chloro-N-((3,4-dichlorobenzyl)oxy)nicotinamide) possessed excellent herbicidal activity against Lemna paucicostata (duckweed), with an IC50 value of 7.8 μM, whereas the commercial herbicides clomazone and propanil had values of 125 and 2 μM, respectively. The structure-activity relationships reported in this paper could be used for the development of new herbicides against monocotyledonous weeds.

Synthesis and in vitro antiproliferative activity of flavone and 6-hydroxyflavone oxime ethers derivatives

Herein we report the synthesis of a series of O-alkyl oximes of flavone and 6-hydroxyflavone using a simple experimental protocol under solvent free conditions with yields up to 87percent. Cytotoxicity of all compounds was evaluated against MDA-MB-231, PC

O-alkylhydroxylamines as rationally-designed mechanism-based inhibitors of indoleamine 2,3-dioxygenase-1

Indoleamine 2,3-dioxygenase-1 (IDO1) is a promising therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression. Recently important advances have been made in understanding IDO1's catalytic mechanism. Although much remains to be discovered, there is strong evidence that the mechanism proceeds through a heme-iron bound alkylperoxy transition or intermediate state. Accordingly, we explored stable structural mimics of the alkylperoxy species and provide evidence that such structures do mimic the alkylperoxy transition or intermediate state. We discovered that O-benzylhydroxylamine, a commercially available compound, is a potent sub-micromolar inhibitor of IDO1. Structure-activity studies of over forty derivatives of O-benzylhydroxylamine led to further improvement in inhibitor potency, particularly with the addition of halogen atoms to the meta position of the aromatic ring. The most potent derivatives and the lead, O-benzylhydroxylamine, have high ligand efficiency values, which are considered an important criterion for successful drug development. Notably, two of the most potent compounds demonstrated nanomolar-level cell-based potency and limited toxicity. The combination of the simplicity of the structures of these compounds and their excellent cellular activity makes them quite attractive for biological exploration of IDO1 function and antitumor therapeutic applications.

NBu4NI-catalyzed intermolecular C-O cross-coupling reactions: Synthesis of alkyloxyamines

A practical and simple nBu4NI-catalyzed C-O bond formation for the synthesis of alkyloxyamines was achieved under metal-free conditions. The reaction is applicable to the coupling of a range of benzylic and allylic hydrocarbons with N-hydroxyphthalimide and is tolerant of various functional groups. The reaction mechanism was primarily investigated and a radical process was proposed.

Catalytic ortho -acetoxylation of masked benzyl alcohols via an exo -directing mode

A Pd-catalyzed ortho-acetoxylation of masked benzyl alcohols to synthesize various 2-hydroxyalkylphenol derivatives is reported. The 2,6-dimethoxyl benzaldoxime proved to be an efficient exo-type directing group for arene (sp2) C-H functionalization. Two strategies were demonstrated to remove the directing group through N-O and C-O bond cleavages. A high catalyst turnover (>1000) was obtained to illustrate the practicality of this method.

Intramolecular aza-[4+3] cycloaddition reactions of α- halohydroxamates

Polyheterocyclic scaffolds were prepared by intramolecular aza-[4+3] cycloaddition reactions of aza-oxyallylic cations with cyclic dienes. The aza-oxyallylic cation was generated in situ by the dehydrohalogenation of α-halohydroxamates. The highly functionalized heterocyclic products undergo a variety of reactions that provide useful scaffolds for target-directed synthesis, including macrocyclic furans and polyhydroxylated azepanes.
