Abstract
α-Deprotonation of 2-ethylpyridine chromium tricarbonyl with lithium diisopropylamide followed by addition of non-enolisable aldehydes, benzaldehyde and 2,2-dimethylpropanal, leads to single diastereoisomers of the corresponding aldol-type products, which on oxidative decomplexation give erythro-1-phenyl-2-(2-pyridyl)-1-propanol and erythro-2,2-dimethyl-4-(2-pyridyl)-3-pentanol, respectively, in good yield.Keywords
