method for one-pot preparation of Julia-Kocienski sulfides and sulfones from alcohols and thiols is reported. A variety of primary alcohols were converted to the corresponding mesylates by methansulfonyl chloride and triethylamine in THF. After the reaction is complete, thiol (1 or 10) and either NaH or t-BuOK were added. The Julia-Kocienski sulfides 3, 9 and 11 were prepared by one-pot two steps procedure
报道了一种从醇和硫醇单锅制备Julia-Kocienski硫化物和砜的方法。甲磺酸磺酰氯和三乙胺在THF中将各种伯醇转化为相应的甲磺酸酯。反应完成后,加入硫醇(1或10)和NaH或t- BuOK。茱莉亚-Kocienski所硫化物3,9和11分别通过一釜两步过程在76-96%的产率(16个实施例)制备由醇。此外,在硫化物形成后,将反应混合物用对甲苯磺酸中和并用H 2 O 2处理。和在EtOH中的钼酸铵,除反式-2-hexen-1-ol外,均以良好的收率得到Julia-Kocienski砜4。
