2‐(Disubstituted amino)‐4,5‐dihydro‐3‐furancarbonitriles 1a − i reacted with acetyl chloride to yield the corresponding ring‐opening products 2a − i . The cyclization of compounds 2a − f with bases gave the corresponding N , N ‐disubstituted 1‐cyanocyclopropanecarboxamides 3a − c and ( E )‐1‐cyano‐2‐phenylcyclopropanecarboxamides 3d − f . The same compounds 3d − f were also obtained by treatment of compounds 2g − i with sodium methoxide. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
