Magnesium allenyl enolates

Other magnesium allenyl enolates, such as 22, obtained by transmetallation of the lithium species have been used successfully in the preparation of a,-unsaturated acyl silanes (equation 28). ... [Pg.450]

An interesting class of chiral enolates are allenyl enolates. These ambident nucleophiles bear an axis of chirality. Krause and coworkers have found that an axis to center chirality transfer takes place in the aldol reaction of chiral magnesium allenyl enolate with pivalic aldehyde . The aldol reaction proceeds with good diastereofacial selectivity if... [Pg.505]
