Useful Chemistry of 3-(1-Methylethylidene)-4-acetoxy-2-azetidinone: A Formal Synthesis of (+/-)-Asparenomycin C

3-(1-Methylethylidene)-4-acetoxy-2-azetidinone (5) was prepared from the addition of chlorosulfonyl isocyanate to 1-acetoxy-3-methylbuta-1,2-diene.Isolated as a stable crystalline solid, this material is a versatile intermediate and is used in a formal sy
