2,4-Dialkyl-9-oxa-2,4-diazabicyclo[3,3,1]nonan-3-ones were easily prepared by the acid-catalyzed reactions of glutaraldehyde with 1,3-dialkylureas in aqueous conditions, whereas in the absence of water only the copolymerization was observed.
在水性条件下,戊二醛与1,3-二烷基脲的酸催化反应很容易制备2,4-二烷基-9-氧杂-2,4-二氮杂双环[3,3,1]壬基-3-酮。在不存在水的情况下,仅观察到共聚。
