摘要

The synthesis and reactions of several α, β-unsaturated chloromethyl sulfones is 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 with base giving Ramberg– ...
