synthesis and reactions of several α,β-unsaturated chloromethyl sulfones are presented, for example [(chloromethyl) sulfonyl]-1,3-propadiene, [(chloromethyl) sulfonyl]ethene, [(dichloromethyl)sulfonyl]ethene and (E,Z)-1,2-bis[(chloromethyl)sulfonyl]ethene. These compounds serve as “prepackaged” Ramberg–Bäcklund reagents, which, following an appropriate first step, such as Diels–Alder addition, react
摘要 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、[(氯甲基)磺酰基]乙烯、[(二氯甲基)磺酰基]乙烯和(E ,Z)-1,2-双[(氯甲基)磺酰基]乙烯。这些化合物用作“预包装”的 Ramberg-Bäcklund 试剂,在适当的第一步之后,如 Diels-Alder 加成,与碱反应,得到 Ramberg-Bäcklund 产品。
