Functionalized enantiopure organosilanes are important building blocks with applications in various fields of chemistry; nevertheless, asymmetric synthetic methods for their preparation are rare. Here we report the first organocatalytic enantioselective synthesis of tertiary silyl ethers possessing “central chirality” on silicon. The reaction proceeds via a desymmetrizing carbon–carbon bond forming
The enantioselective construction of silicon-stereocenter by asymmetric enamine catalysis is reported. The reaction proceeds via an unprecedented desymmetric intramolecular aldolization of prochiral siladials for the diverse synthesis of multifunctional silicon-stereogenic silacycles.
