Used for synthesis of sultam analogs of β-lactams; synthesis of biologically active sulfonamides. | [Synthesis]
Methyl 2-(chlorosulfonyl)acetate is synthesized from chlorosulfonylacetyl chloride by reaction with 1 equiv of methanol; may also be prepared by chlorination of sodium methoxycarbonylmethanesulfonate with Phosphorus(V) Chloride or by direct chlorination of methyl thioglycolate. | [storage]
moisture sensitive; causes burns. |
