An interesting and useful level of geometric control can be read in the reaction of enolates derived from bistrimethylsilyl acetates and aldehydes leading to a-trimethylsilyl esters and derived compounds depending upon the cation employed. Mechanistic experiments are described which suggest that chelation may play a role in the origin of the observed selectivities.
