-anti stereoinduction in the aldol reaction of beta-tris(trialkylsilyl)siloxy methylketones can be achieved with high diastereoselectivities. Tris(trialkylsilyl)silyl groups are easily prepared and play an important role in the selectivities of these reactions. Furthermore, all of the 1,3,5-triol stereoisomers can easily be prepared from beta-siloxy methylketones in no more than three steps.
