■ Novel Reactions of Carbon Suboxide. VII. Synthesis of Heterocyclic Rings by Reaction with Bifunctional Aliphatic Compounds

Leonardo Bonsignore, Salvatore Cabiddu, Giuseppe Loy, and Daniela Secci

*Tossicologica e Applicata, Instituto di Chimica Farmaceutica, Università di Cagliari, Via Ospedale 72, I-09124 Cagliari, Italy

Abstract

Carbon suboxide reacts with various bifunctional aliphatic compounds yielding derivatives of furan, pyran, axepin, diazepine, axazepine and dioxepin. A description of the synthesis is given. The structure of the reaction products was determined by elemental analysis and spectrascopic methods.
