Dehydration of Aldoximes Using PhSe(O)OH as the <i>Pre</i>-Catalyst in Air

PhSe­(O)­OH was found to be a good <i>pre</i>-catalyst for aldoxime dehydrations in open air. Compared with the previously reported (PhSe)₂-H₂O₂ system, it is more stable and milder, affording broader application scopes due to a higher functional group tolerance. The control experiments for mechanism study disclosed that air was the key factor for the reaction to maintain enough concentration of PhSeOH, which should be the real catalytic species

Copper-Catalyzed <i>N</i>‑Arylation of Azoles and Mannich-Type Coupling of Ketones and Azoles under Metal-Free Conditions

A new process has been developed for the copper-catalyzed direct <i>N</i>-arylation of five-membered heterocycles with azoles. Five-membered heterocycles bearing an acetyl group also underwent a Mannich-type reaction with activated azoles to give the corresponding β-amino ketones under metal-free conditions. These reactions exhibited wide substrate scope, high functional group tolerance, and ease of operation, making them useful tools with numerous potential applications in synthetic chemistry

DG: Do you know about the dietary guidelines for Chinese residents? LF: Choosing a diet with a lot of fresh fruits and vegetables is good for one’s health. VS: Eating a lot of sugar is not good for one’s health. VF: Eating a variety of foods is good for one’s health. HF: Choosing a diet high in fat is not good for one’s health. SF: Choosing a diet with a lot of staple foods (rice and rice products and wheat and wheat products) is not good for one’s health. AP: Consuming a lot of animal products daily (fish, poultry, eggs and lean meat) is not good for one’s health. AM: Reducing the amount of fatty meat and animal fat in the diet is good for one’s health. MDP: Consuming milk and dairy products is good for one’s health. BBP: Consuming beans and bean products is good for one’s health. PA: Physical activities are good for one’s health. IPA: Sweaty sports or other intense physical activities are not good for one’s health. HB: The heavier one’s body is, the healthier he or she is.</p
