Thierry P. Berger,Marine MinierTh asmmetric carbon atom C(a,b,c,d) (Scheme 1, top) dominates sterochemistry since 120 years. Other main group elements, surrounded by four different substituents have been obtained ip optically active form, e.g. silicon in the compoundSi(a-Np,Ph,Me,Cl) (Scheme 1, bottom left), a field which has been pioneered by L.H. Sommer and R.J.P Corriu .

Abderrahmane Nitaj,David Pointchevalyst for a related process. The geometric preference of this catalyst is evidenced in the greater effectiveness of one isomer, but another isomer is preferred for bifunctional catalysis of enolization and of an internal aldol condensation..Central to the mechanistic study is the conversion of the nor
