Description
Methyl (E)-4-chloro-3-methoxy-2-butenoate (CAS 110104-60-4) from TCI is a bifunctional four-carbon synthon offered by AMI Scientific. The allylic chloride provides a reactive electrophilic site while the methoxy-substituted unsaturated ester behaves as a vinylogous system and Michael acceptor. This combination allows sequential nucleophilic substitution and conjugate addition, making it convenient for building functionalised chains and heterocyclic rings. The defined E geometry helps maintain stereochemical consistency throughout multistep synthetic routes.
