Shaykhutdinova, Polina published the artcileFurther Structural Modification of Sulfur-Stabilized Silicon Cations with Binaphthyl Backbones, Related Products of chlorides-buliding-blocks, the publication is Synthesis (2019), 51(10), 2221-2229, database is CAplus.
The synthesis and spectroscopic characterization of two novel cationic Si-S Lewis pairs with a chiral 4,4′-disubstituted binaphthyl silepine backbone are described. Both Lewis acids induce significant enantioselectivity in the model Diels-Alder reaction of cyclohexa-1,3-diene and chalcone but addnl. substitution of the binaphthyl backbone exerts a minimal effect on enantioinduction compared to previously reported Lewis acids. Another Si cation with a chiral spirocyclic backbone induces enantioselectivity in the same range but its synthesis is laborious.
