Lewis Base-Catalysed Aldol Additions,d general procedures for the preparation of trichlorosilyl enolates of carbonyl compounds by metal exchange reactions. These are reactions between corresponding enol stannanes of ketones with SiCl., or metal exchange of trimethylsilyl enolethers with SiCl. in the presence of catalytic amounts of mer

Direct Aldol Addition,l additions high degrees of regio- and diastereoselectivities were measured. C—C bond formation was observed at the sterically more encumbered α-position of the ketones only.. Later on Tanabe and coworkers reported the in situ generation of silyl enol ethers using catalytic amounts of trimethylchlor
