A novel efficient beta -lactam synthesis was achieved by two successive processes (sulfeno-cycloamination), addition of phenysulfenyl chloride to alpha , beta -unsaturated amides followed by base treatment. Key synthetic intermediates of monobactams and nocardicin derivatives were obtained via this method. construction of the 1-carbapenam ring system by the sulfenocycloamination is also described.
