Abstract: The results of the reaction of aminomethyl heterocycles and 4,6-dimethyl-2-formylpyrimidine and of activated secondary amines with different aryl/heteroaryl or aliphatic aldehydes and N-methylmaleimide or maleimide are described. In the former case the reactions gave single diastereomers via endo-transition states whilst the latter gave a mixture of diastereomers, which are believed to arise from anti-dipoles via endo/exo transition states. The stereochemistry of the cycloadducts was determined by 1H NMR and confirmed by X-ray crystallography. [Copyright &y& Elsevier]
