[2+2]-Cycloaddition of ‘Maleic Isoimides’ with Ketenes and Reactions of Spiro-b̃-lactams to Muconic and Tetramic AcidsThe [2 + 2]-cycloaddition of iminolactones of type 2 (‘maleic isoimides’) with various ketenes affords spiro-b̃-lactams 4-6. These highly functionalized compounds react with CH3ONa giving ketoadipinic acid derivatives 12 and/or pyrrolidinediones 7, depending on the reaction temperature and the nature of substituents.
