In the presence of potassium carbonate the reaction of isopropylidene 5-tosyloxymalonate with alkyl halides under PTC conditions gives sulphones. The reaction represents the first example of SO scission of tosylate via SO. As a result, a novel synthon equivalent to p-CH3C6H4SO−2 is found.
在碳酸钾的存在下,异丙基亚甲基5-甲苯磺酰丙二酸酯与烷基卤化物在PTC条件下反应得到砜。该反应代表了通过S = O对甲苯磺酸酯进行S = O分裂的第一个实例。结果,发现了等效于p-CH 3 C 6 H 4 SO - 2的新型合成子。
