    Benzyloxyacetyl chloride is a reagent used to construct substituted 2-azetidinones for further elaboration into annulated β-lactams. It is a commonly employed reagent for asymmetric synthesis of β-lactams. It is also used in preparation of (S)-3-(methylamino)-3-((R)-pyrrolidin-3-yl)propanenitrile, key intermediate in the preparation of fluoroquinolone antibiotic for respiratory tract infections, non-racemic helicene and β-lactams.
