A concise and efficient one-pot four-step synthesis of 2,4-disubstituted thiazoline via a cascade disulfide bond cleavage/thiocarbonylation/Staudinger reduction/aza-Wittig reaction is established. Treatment of various carboxylic acids with β-azido disulfides under this one-pot procedure obtained the desired thiazolines in good to excellent isolated yields.
建立了通过级联二硫键裂解/硫代羰基化/施陶丁格还原/氮杂-维蒂希反应的2,4-二取代噻唑啉的简洁高效的一锅四步合成方法。在该一锅法中,用β-叠氮基二硫化物处理各种羧酸可得到所需的噻唑啉,分离产率高至优异。
