A novel, facile, highly efficient and stereoselective protocol for the synthesis of cis-3-allyl-3-phenylsulfinyl-β-lactams and 3-allylidene-β-lactams from cis-3-allyl-3-phenylthio-β-lactams using Selectfluor both as an oxidizing agent and as an eliminating agent with temperature as a control parameter over the reaction outcome has been reported. The methodology is able to conquer the earlier reported
一种新颖、简便、高效和立体选择性的方案,用于从顺式-3-烯丙基-3-苯硫基-β-内酰胺合成顺式-3-烯丙基-3-苯基亚磺酰基-β-内酰胺和 3-烯丙基-β-内酰胺据报道,Selectfluor 既可用作氧化剂又可用作消除剂,温度可作为反应结果的控制参数。该方法能够克服早先报道的反应时间长(24-90 小时)和对产品比例缺乏控制的缺点。合成的化合物将作为增强生物活性和效力的化合物的重要合成子。
