, p. 189 - 198 (2007/10/02)
The regio- and diastereoselectivity of the addition of N,N-dialkylphenylthioacetamide enolates to some conjugate carbonyl compounds are studied.The results are compared with oxoanalogs and the differences are rationalized in terms of specific behaviour of

N,N-diisopropylamides and -thioamides show hindered rotation around the N-CH bonds, and presence of mixtures of conformational isomers can be demonstrated at temperatures below 273 K in solution. 1H and 13C NMR spectra of these conformers are measured and
