Abstract

Convenient and efficient methods of synthesis for pyrrolizidine, 8-alkylpyrrolizidines, ln2 and 1-alkylpyrrolizidinesS have been described in earlier papers. The present investigation is concerned with the condensation of nitroparaffins with methyl methacrylate and the subsequent formation of 2-alkyl-, 2, 6-dialkyl-, 2, 8-dialkyl-, and 2, 6, 8-trialkylpyrrolizidines (IV, V). The compound 2-methylpyrrolizidine (IV, R= H) had been prepared previously by ...
