Alkyllithium reagents react preferentially 1,4 and in a highly syn stereoselective manner with γ-alkoxy enoates (alkyl 4,5-isopropylidenedioxy-2-pentenoates) derived from glyceraldehyde acetonide (2,3-isopropylidenedioxy-1-propanal), to provide synthetically useful chiral building blocks. We suggest a transition-state model for such additions based on MM2 calculations.
