A highly selective, environmentally friendly, and scalable electrochemical protocol for the construction of α-acyloxy sulfides, through the synergistic effect of self-assembly-induced C(sp3)–H/O–H cross-coupling, is reported. It features exceptionally broad substrate scope, high regioselectivity, gram-scale synthesis, construction of complex molecules, and applicability to a variety of nucleophiles

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。
Iodine-Catalyzed Oxidative Amination of Sodium Sulfinates: A Convenient Approach to the Synthesis of Sulfonamides under Mild Conditions
The iodine-catalyzedoxidativeamination of sodiumsulfinates in the presence of sodium percarbonate as the oxidant has been developed. The reaction shows good substrate scope and tolerates a wide range of functionalities in both amine and sodiumsulfinate substrates. Aliphatic amines, heteroaromatic amines and hydrochloride salts of amines can be employed as the amine sources in this transformation

The present invention relates to novel oxazolidinones (Formula I): or a pharmaceutically acceptable salt having ring A characterized by N-containing monocyclic, bicyclic or spirocyclic substituents, to their preparation, and to their use as drugs for treating Mycobacterium tuberculosis and other microbial infections, either alone or in combination with other anti-infective treatments.
A convenient and green synthetic route has been developed to synthesize sulfonamides in an aqueous medium at room temperature, without the use of transition metal catalysts and oxidants.
