By using conformational and minimization searches with MacroModel 8.5 under the MM2* force-field, 3 was estimated to display greater degrees of freedom, a lower global energy minimum, and a larger transannular cavity than the C4-macrolide-epimer, epi-3.

(c) The stereochemical result (α-facial attack) is similar to that found when sufonium ylids were used and is presumably dominated by the Burgi-Dunitz trajectory being more hindered by the C11-MOM ether on the β-face.
