synthesis and reactions of several α,β-unsaturated chloromethyl sulfones is presented, for example [(chloromethyl)sulfonyl]-1,3-propadiene (4), [(chloromethyl)sulfonyl]ethene (5), [(dichloromethyl)sulfonyl]ethene (6) and (E,Z)-1,2-bis[(chloromethyl)sulfonyl]ethene (7). These compounds serve as ‘prepackaged’ Ramberg–Bäcklund reagents, which following an appropriate first step, such as Diels–Alder addition
介绍了几种α,β-不饱和氯甲基砜的合成和反应,例如[(氯甲基)磺酰基] -1,3-丙二烯(4),[(氯甲基)磺酰基]乙烯(5),[(二氯甲基)磺酰基乙烯(6)和(E,Z)-1,2-双[(氯甲基)磺酰基]乙烯(7)。这些化合物用作“预包装”Ramberg-Bäcklund试剂,经过适当的第一步(例如添加Diels-Alder)后,它们会与碱发生反应,从而得到Ramberg-Bäcklund产品。
