Studies concerning the addition of ethyl acetate lithium enolate to the carbonyl groups of 2-methylsulfinyl-2-sulfanyl-cyclohexanones were also undertaken. In the case of 2-methylsulfinyl-2-methylsulfanylcyclohexanone, a mixture of conformers was evidenced by I. R. spectroscopy. On the basis of theoretical considerations, it could be advanced that, in the most abundant conformer, the SOCH 3 and SCH 3 groups lie, respectively, in equatorial and axial arrangements. Therefore, the observed enantiomeric excess can be explained considering that the enolate performs an axial attack to the carbonyl groups of the ketone conformers.
