|Title:||Chiral Allylsilane Additions To Chiral α-substituted Aldehydes|
|Abstract:||Chiral allylsilane 3 reacted with chiral α-methyl-β-siloxy-aldehydes to afford the corresponding 1,4-syn-products with good diastercoselectivities independent of the absolute stereochemistry of these aldehydes. The best selectivities are observed when the reactions are carried out by transmetallation of the allylsilane 3 using Tin (IV) Chloride in CH2Cl2, at -78°C, before addition of the aldehydes.|
