U. Girreser et al., A FACILE ONE-POT SYNTHESIS OF 1-ARYL-2-(DIMETHYLAMINOMETHYL)PROP-2-EN-1-ONES FROM ARYL METHYL KETONES, Synthesis, (5), 1998, pp. 715-717
A generally applicable synthesis of 1-aryl-2-(dimethylaminomethyl)prop
-2-en-1-ones 2 involving reaction of aromatic methyl ketones 1 with pa
raformaldehyde and dimethylamine in dimethylformamide is described. Th
e majority of experiments were conducted with these reagents, but the
process can also be performed using dimethyl(methylene)ammonium chlori
de.
