cis-1,4-Dichloro-2-butene
CAS 1476-11-5
A four-carbon intermediate can already encode two reaction sites, an alkene, and a fixed three-dimensional geometry.
cis-1,4-Dichloro-2-butene packs several synthetic instructions into four carbons. Two allylic chlorides provide substitution sites, the central alkene provides a separate reaction platform, and cis geometry fixes the terminal groups on the same side. Small building blocks can be information-rich: reactivity and three-dimensional geometry are both preloaded before the next bond is made.
