Preparation and structures of 2-substituted 5-benzyl-3-methylimidazolidin- 4-one-derived iminium salts, reactive intermediates in organocatalytic transformations involving α,β-unsaturated aldehydes

Preparations of the title compounds, 5-7 (Scheme 1 and Table 1), of their ammonium salts, 9-11 (Scheme 2 and Table 2), and of the corresponding cinnamaldehyde-derived iminium salts 12-14 (Scheme 3 and Table 3) are reported. The X-ray crystal structures of 15 cinnamyliminium PF6 salts have been determined (Table 4). Selected 1H-NMR data (Table 5) of the ammonium and iminium salts are discussed, and structures in solution are compared with those in the solid state. Copyright
