摘要：
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-i with bases gave the corresponding N,N-disubstituted 1-cyanocyclopropanecarboxamides 3a-c and (E)-1-cyano-2-phenylcyclopropanecarboxamides MA The same compounds 3d-f were also obtained by treatment of compounds 2g-i with sodium methoxide.
