Abstract

1,3-Dipolar cycloadditions of a number of C-aryl, C-carbamoyl-, and C,C-bis(methoxycarbonyl)nitrones and substituted Nvinylpyrroles proceed with high efficiency and regioselectivity with the formation of only one isomeric substituted 5-(1H-pyrrol-1- yl)isoxazolidine cycloadduct.

Abstract

Abstract: 1,3-Dipolar cycloadditions of dialkyl-substituted 2-benzylidenecyclopropane-1,1-dicarboxylates and a number of C-carbamoyl nitrones proceed with high efficiency and selectivity with the formation of single isomeric spiro[cyclopropane-1,4-isoxazolidine] cycloadduct. Obtained cycloadducts easily undergo cyclopropyl ring opening–cyclization to form new β-lactams fused with isoxazolidine ring in high yields. [Copyright &y& Elsevier]
