Sažetak

Six new tertiary 2-furfurylamines of the general formula
2-C 4H 30 · CH2 NRAr, w h ere R represents methyl, ethyl or ally!,
and Ar phenyl, p-tolyl or p-methoxyphenyl groups, have been prepared
by alkylation of the appropriate secondary aryl-(2-furfuryl)-
amines with alkyl or ally! halides.
It was found that the oily allyl-aryl-(2-furfuryl)-amines, on
standing at room temperature, spontaneously isomerized to crystalline
N-aryl-4H-5,7a-epoxyisoindolines, formed by a reversible intramolecular
Diels-Alder reaction.
