presence of visible light is used to initiate thiol–ene and thiol–yne reactions. Thiyl radicals are generated upon quenching the photoexcited catalyst with a range of thiols. The highlighted mild nature of the reaction conditions allows a broad substrate scope of the reactants. Relying on this efficient metal-free condition, both thiol–ene and thiol–yne reactions between carbohydrates and peptides could

A newsynthetic route for the preparation of S-benzylated β-acyloxy mercaptans starting from the one-pot reaction of thioacids and epoxides using a silica gel/Et3N combined catalyst is described. The thiol functionality in the crude product is then protected via benzylation and the corresponding thioethers are isolated after chromatography.
描述了一种新的合成路线,该路线用于使用硅胶/ Et 3 N组合催化剂从硫代酸和环氧化物的一锅反应开始制备S-苄基化β-酰氧基硫醇。然后通过苄基化作用保护粗产物中的硫醇官能度,并在色谱分离后分离出相应的硫醚。
