## Abstract A general method is described for the synthesis of 1‐aryl‐2‐alkyl‐1,4,5,6‐tetrahydropyrimidines 1, by cyclization of __N__‐acyl‐__N__′‐aryltrimethylenediamines 2 with trimethylsilyl polyphosphate. Precursors 2 were obtained by aminolysis of the corresponding __N__‐(3‐bromopropyl)amides
## Abstract magnified image Sulphamoyl chlorides and chlorosulphonyl isocyanate react with monosubstituted hydrazones and alkylhydrazonates to sulphamoyl hydrazones and sulphamoyl hydrazonates respectively. Reaction of benzil monoalkylhydrazones with chlorosulphonyl isocyanate results in formation
