Abstract
Previously unknown 3-N-alkylamino-, 3-N,N-dialkylamino-4-but-2-enolides containing spirocyclic moiety have been synthesized by nucleophilic addition of amines at the triple bond of methyl ester of β-(1-hydroxycyclohexyl)propiolic acid or by the reaction of amines with the corresponding 3-methoxy-4-but-2-enolide.
