Hypothesized conformations for the conformational isomers of compound 3. For easy observation two methyl groups in 2-position of the oxazolidineare not shown up in the projections. The bulky group –COCH2SOPh is located above the carbamate group plane in the half-chair form, while below the amide plane in the envelope form. In both conformations α-H is in an axial position.
