Acylureas (ureides) are valued for their important biological activities. Whereas cyclic acylureas have frequently been the object of solid-phase chemistry, only few reports have focused on the solid-supported preparation of acyclic representatives. We have prepared different types of acylureas on Rink amide resin in three or four steps. The products are either N-acylated (9, 18), N-acylated-N′-alkylated (10, 19), or N-acylated-N-alkylated (22). Characteristic NMR parameters of isomeric acylureas 10, 19, and 22 are discussed.

The anticonvulsant effects of benzyl- and benzhydryl ureides in mice models of seizures (maximal electroshock seizure test, pentylenetetrazol test, picrotoxin-induced seizure test) and the influence on spontaneous locomotor activity has been assessed. Fur
Preparation of a novel polystyrene-based urea resin

A urea-functionalized polystyrene-resin with a Rink linker was prepared by adaptation of a solution-phase synthesis to solid-phase chemistry. Thereby, a resin-bound acylurea was formed by reacting a Rink-amide resin with trichloroacetyl isocyanate, followed by the thermal removal of the trichloroacetyl group and thus generating the unsubstituted solid-supported urea.
