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

The catalytic effects of various metal halides and solvents on the reaction of benzoyl chloride with sodium cyanate were studied.It has been found that SnCl4, and ZnCl2 catalyze the reaction to give the corresponding acyl isocyanates in good yields.The scope of the reaction was studied and a number of aroyl isocyanates and their derivatives were prepared.A few non aromatic isocyanates and their derivatives were also prepared.
