Synthesis method of 1, 3, 4-oxadiazole heterocyclic compound

The invention belongs to the technical field of organic synthesis and medicines, and particularly relates to a synthesis method of a 1, 3, 4-oxadiazole heterocyclic compound. The 1, 3, 4-oxadiazole heterocyclic compound is obtained by taking a benzaldehyde derivative and a diazonium trivalent iodine reagent as raw materials, taking dichloromethane as a solvent without any catalyst under illumination and carrying out reaction at room temperature. According to the method provided by the invention, the 1, 3, 4-oxadiazole heterocyclic derivative can be obtained by a one-step method under the condition of room temperature through reaction for 10-15 hours, and the yield is 48-89%. According to the reaction, the 1, 3, 4-oxadiazole heterocyclic derivative is simply, conveniently and rapidly synthesized in one step under the illumination condition by using simple and easily available raw materials, and a simple, efficient and mild novel synthesis method is provided for synthesizing the 1, 3, 4-oxadiazole heterocyclic derivative.

N-Heterocyclic Carbene-Catalyzed Cyclization of Aldehydes with α-Diazo Iodonium Triflate: Facile Access to 2,5-Disubstituted 1,3,4-Oxadiazoles

Herein, we report a novel organocatalytic process for synthesis of complex 1,3,4-oxadiazoles from readily accessible aldehydes. By exploiting the nucleophilicity of the putative Breslow intermediate and the inherent electrophilicity of α-diazo iodonium triflate, we have found that N-heterocyclic carbene catalyst promotes efficient cyclization of various aldehydes and α-diazo iodonium triflates. The reaction proceeds under mild conditions with a wide range of functional group tolerance. The heterocyclic products can be readily further functionalized, rendering the protocol highly valuable.

Design, synthesis, and biological evaluation of phenyloxadiazole derivatives as potential antifungal agents against phytopathogenic fungi

Abstract: A novel series of picarbutrazox-inspired oxadiazole hybrids was synthesized and the derivatives’ biological activity against phytopathogenic fungi was investigated. The molecules were designed by retaining the active fragment of tetrazolyl phenyloxime ether of lead compound picarbutrazox, while introducing the potentially active oxadiazole-derived fragment. Bioassay results revealed that some of the title compounds showed potent in vivo antifungal activities to control cucumber downy mildew. Therefore, this novel oxadiazole phenyloxadiazole derivative can be used as a potential antifungal agent to control cucumber downy mildew and other phytopathogenic fungi for crop protection.

Design, Synthesis, and Study of the Insecticidal Activity of Novel Steroidal 1,3,4-Oxadiazoles

A series of novel steroidal derivatives with a substituted 1,3,4-oxadiazole structure was designed and synthesized, and the target compounds were evaluated for their insecticidal activity against five aphid species. Most of the tested compounds exhibited potent insecticidal activity against Eriosoma lanigerum (Hausmann), Myzus persicae, and Aphis citricola. Compounds 20g and 24g displayed the highest activity against E. lanigerum, showing LC50 values of 27.6 and 30.4 μg/mL, respectively. Ultrastructural changes in the midgut cells of E. lanigerum were detected by transmission electron microscopy, indicating that these steroidal oxazole derivatives might exert their insecticidal activity by destroying the mitochondria and nuclear membranes in insect midgut cells. Furthermore, a field trial showed that compound 20g exhibited effects similar to those of the positive controls chlorpyrifos and thiamethoxam against E. lanigerum, reaching a control rate of 89.5% at a dose of 200 μg/mL after 21 days. We also investigated the hydrolysis and metabolism of the target compounds in E. lanigerum by assaying the activities of three insecticide-detoxifying enzymes. Compound 20g at 50 μg/mL exhibited inhibitory action on carboxylesterase similar to the known inhibitor triphenyl phosphate. The above results demonstrate the potential of these steroidal oxazole derivatives to be developed as novel pesticides.

Intramolecular cycloadditions of photogenerated azaxylylenes with oxadiazoles provide direct access to versatile polyheterocyclic ketopiperazines containing a spiro-oxirane moiety

Photogenerated azaxylylenes undergo intramolecular cycloadditions to 1,3,4-oxadiazole pendants, which are accompanied by concomitant release of dinitrogen, yielding functionalized ketopiperazinoquinolinols containing an oxirane moiety fused to the quinolinole moiety while spiro-connected to diketopiperazine. These primary photoproducts are reactive versatile intermediates which can be further derivatized under nucleophilic SN1- or SN2-like ring opening of the oxirane moiety. The oxidized quinolinones undergo new rearrangements under the conditions of the Schmidt reaction, leading to unprecedented triazacanoindolinones.
