Applications
Description3-Chloropropionyl chloride is an important bifunctional reagent. It is capable of acylation and possesses a 2-chloro-ethyl fragment (CH2CH2Cl), which can be subjected to nucleophilic substitution and serves as a masked vinyl group. It can be used as a starting material in many reactions to construct a variety of (hetero)cyclic compounds.
Uses3-Chloropropionyl chloride is a reagent used in the synthesis of Beclamide (B119400), which is a chlorinated benzylpropanamide used as an anticonvulsant drug. It is used in the treatment of tonic-clonic seizyres and has sedative properties.
Preparation methods
Preparation3-Chloropropionyl chloride (1) is commercially available and can be prepared from β-propiolactone (2) and thionyl chloride.1 Other standard methods available for the preparation of acyl chlorides can also be applied: the reaction of acrylic acid (3) or 3-chloropropionic acid (4) with thionyl chloride, phosphoryl chloride, phosgene, or phosphorus trichloride.
