The Stereochemistry of the Reaction of α-Silyl Lithium Reagents with Cyclic Tert-butyldimethylsilyl Acyloins

(Phenylthiomethyl)trimethylsilane

“…2 The vinyl sulfides are not formed stereoselectively unless there are proximate bulky substituents. 13 Peterson alkenation products have also been observed in the reaction of (2) with amides, ureas, and carbonates. 14…”
