We have developed an eco-friendly and chemo-selective photocatalytic synthesis of sulfoxides or sulfones via oxidation of sulfides (thioethers) at ambient temperature using air or O2 as the oxidant. An inexpensive thioxanthone was used as the photocatalyst. Our method offers excellent chemical yields and good functional group tolerance. The hydrogen bonding between hexafluoro-2-propanol (HFIP) and
我们开发了一种环保且化学选择性的光催化合成亚砜或砜,通过在环境温度下使用空气或 O 2作为氧化剂氧化硫化物(硫醚)。廉价的噻吨酮被用作光催化剂。我们的方法提供了出色的化学产率和良好的官能团耐受性。六氟-2-丙醇 (HFIP) 和亚砜之间的氢键可能在最大限度地减少亚砜的过度氧化方面发挥重要作用。

The present invention provides isoxazoline derivatives and uses thereof in agriculture; in particular, the present invention provides a compound having formula (I), or a stereoisomer, an N-oxide or a salt thereof, preparation methods thereof, and compositions containing these compounds and uses thereof in agriculture, particularly uses as herbicide active ingredients for controlling unwanted plants; wherein R1, R2, R3, R4, n, R5, R6 and Hy are as described in the invention.
Indoleamine2,3-dioxygenase1 (IDO1) is an immunosuppressive enzyme that is highly overexpressed in various cancer cells and antigen-presenting cells. It has emerged as an attractive therapeutic target for cancer immunotherapy, which has prompted high interest in the development of small-molecule inhibitors. To discover novel IDO1 inhibitors, we designed and synthesized a series of N'-hydroxyindazolecarboximidamides
