search of environmentally benign insecticides with high activity, low toxicity and low residue, a series of novel anthranilic diamidescontaining allyl ether were designed and synthesized. All the compounds were characterized by 1H NMR spectroscopy, HRMS or elemental analysis. The single crystal structure of 18e was determined by X-ray diffraction. The insecticidalactivities of the new compounds were evaluated
为了寻找高活性,低毒性和低残留的环境友好的杀虫剂,设计并合成了一系列新型的含烯丙基醚的邻氨基苯甲酰胺。所有化合物均通过1 H NMR光谱,HRMS或元素分析进行表征。通过X射线衍射确定18e的单晶结构。评价了新化合物的杀虫活性。结果表明,某些化合物对鳞翅目害虫表现出优异的杀虫活性。在该系列化合物中,18l在测试浓度下对Mythimna独立的Walker和Plutella xylostella Linnaeus表现出100%的杀幼虫活性。
Synthesis, Crystal Structure, and Biological Activity of Novel Anthranilic Diamide Insecticide Containing Propargyl Ether Group
benign insecticides with high activity, low toxicity, and low residue, a series of novel anthranilic diamide containing propargyl ether were designed and synthesized. All compounds were characterized by 1H NMR spectroscopy, high‐resolution mass spectrometry, or elemental analysis. The single crystalstructure of 18g was determined by X‐ray diffraction.

I<sub>2</sub>/TBHP mediated domino synthesis of 2-(2,4-dioxo-1,4-dihydroquinazolin-3(2<i>H</i>)-yl)-<i>N</i>-aryl/alkyl benzamides and evaluation of their anticancer and docking studies
A novel I2/TBHP mediateddominosynthesis of 2-(2,4-dioxo-1,4-dihydroquinazolin-3(2H)-yl)-N-phenyl benzamides by reaction of isatins with o-amino N-aryl/alkyl benzamides was described. This was the first application of o-amino N-aryl/alkyl benzamides participating in oxidative rearrangement with isatins for synthesis of desired products. The synthesized compounds contained amide and quinazoline units

Lewis acid catalyzed spiro annulation of (<i>Z</i>)-3-amino-acrylates with 2-amino arylbenzamides: one-pot synthesis of pyrrole–quinazoline hybrids
procedure has a number of benefits, including quicker reaction times, a broad tolerance range for functional groups, and the ability to synthesize 2,3-dihydroquinazolin-4(1H)-ones that are of biological importance and take part in organic transformations. This is the first use of molecular hybridization involving linking with pyrrolederivatives and dihydroquinazolin-4(1H)-ones.
