The Mannich dimethylaminomethylation of carbonyl compounds is conveniently carried out via enol trimethylsilyl ethers by a combination of chloroiodomethane (CH2ClI) and N,N,N',N'-tetramethylmethanediamine (TMMD) in DMSO as the solvent at ambient temperatute.The mechanism of the transformation is discussed on the basis of product analysis and 1H NMR spectral studies.The reagent system CH2ClI/TMMD also provides a convenient route to the Eschenmoser's salt ().

4-Dimethylamino-3-phenyl-2-butanone was reduced to the corresponding diastereoisomeric alcohols, which were separated by fractional crystallization of the corresponding hydrochloride salts. The configuration of the diastereoisomeric alcohols was determined by PMR spectroscopy. The assignments were confirmed by a consideration of the mass spectral data obtained for the two alcohols. Acylation of the alcohols gave the corresponding esters. Antimicrobial evaluation of the compounds prepared showed that 4-dimethylamino-3-phenyl-2-butanone had a promising level of antifungal activity while the other derivatives showed either a low level of potency or were inactive.
