Synthesis of novel spiro[cyclopropane-pyrrolizin] derivatives via Mg-mediated conjugate addition of bromoform
The conjugate addition of bromoform with 2-aryliene-2,3-dihydro-1 H -pyrrolizin-1-ones in the presence of magnesium afforded novel 2,2-dibromo-3-arylspiro[cyclopropane-1,2′-pyrrolizin]-1′(3′ H )-ones in moderate yield. The structures of all the products were characterized thoroughly by 1 H NMR, 13 C NMR, infrared spectroscopy, and mass spectrum.
