Ester derived titanium enolate aldol reaction: Highly diastereoselective synthesis of syn- and anti-aldols

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.
