Abstract
Abstract 1,3-Diacyl imidazolidines and hexahydropyrimidines were prepared by the reaction of formaldehyde and an N,N''-alkylene-bisamide in the presence of a strong acid catalyst, the substituent acyl groups being acetyl, butyryl, pentanoyl, hexanoyl, heptanoyl, octanoyl, nonanoyl, decanoyl, palmitoyl, stearoyl, and oleoyl. These compounds exhibit antimycotic activity.
