from 4-nitrobenzyl clavulanate, react with salts of thiocarboxylic, thiocarbamic, and sulphinic acids to give thioesters, thiocarbamates, and sulphones; dehydrohalogenation of the halides affords the diene (4), from which sulphur derivatives may also be prepared via a stereospecific 1,4-addition reaction.
由4-硝基苄基棒酸制备的烯丙基卤化物(例如2)与硫代羧酸盐,硫代氨基甲酸酯和亚磺酸的盐反应,生成硫代酸酯,硫代氨基甲酸酯和砜;卤化物的脱卤化氢得到二烯(4),也可以通过立体有规的1,4-加成反应从中制备硫衍生物。
