一般描述
cis-1,4-Dichloro-2-butene on reaction with sodium amide yields trans-1-chloro-1,3-butadiene. Mechanism of condensation of sulfone-activated methylene compounds with cis-1,4-dichloro-2-butene to yield cyclopentene has been investigated.
应用
cis-1,4-Dichloro-2-butene was used in the preparation of functionalized 3,5-disubstituted cyclopent-2-enones.

The preparation of functionalized 3,5-disubstituted cyclopent-2-enones via a solid-phase sulfone linker strategy is described. Polystyrene/divinylbenzene sulfinate 1 underwent S-alkylation followed by alpha,alpha-dialkylation with cis-1,4-dichloro-2-butene to form polymer-bound 3-phenylsulfonylcyclopentenes 8. Subsequent epoxidation of the cyclopentene moiety in 8 was accomplished by

Reaction of adenine (1a) or cytosine (1b) with excess 1,4-dichloro-2-butyne catalyzed by K2CO3 in (CH3)2SO gave the 4-chloro-2-butynyl derivatives 2a and 2b. The latter were converted to the 4-hydroxy-2-butynyl compounds 3a and 3b by refluxing in 0.1 M HCl. Isomerization
