N-Monosubstituted 1,3-diamines were selectively functionalized at the secondary N-atom via 2-Ph-substituted hexahydropyrimidine intermediates. Reaction of the diamines with benzaldehyde, followed by treatment with an electrophile and hydrolysis, provided the desired products with excellent selectivity and in high yields. N4,N9-bis[3-phenylprop-2-enoyl]spermine (4a), which was further converted to N1
The invention relates to novel polyaddition compounds containing uretdione groups, to a process for preparing them and to their use as a starting component in the preparation of polyurethane plastics.
