Enols in aldol condensation

In analogous fashion, titanium and tin enolates are formed by the reaction of enolizable ketones with a tertiary amine and TiCl4 or SnOTf2, respectively. The reactions of titanium enolates are highly selective and comparable to boron enolates in aldol condensations. [Pg.248]

Whereas dibutylboron enolates may be used as specific enolates in aldol condensations, their reactions with alkyl halides are relatively poor. However, the addition of one equivalent of lithium 2-dimethylaminoethoxide results in site-specific mono-a-alkylation in excellent yield. Organotin enamines add to electrophilic alkenes such as acrylonitrile. The use of an optically active... [Pg.89]
