A chelation-controlled and highly diastereoselective synthesis of syn-aldols is described. Aldol reaction of (S)-valinolderived ester with a variety of aldehydes proceeded with high syn-diastereoselectivities (up to 99:1) and isolated yields (94%).
Aldol reactions of bidentate aldehydes and cis-1-arylsulfonamido-2-indanyl ester derived titanium enolates proceed with excellent syn-diastereoselectivities and good to excellent isolated yields.
