Straightforward synthesis of α,β-epoxysilanes from terminal epoxides by lithium 2,2,6,6-tetramethylpiperidide-mediated deprotonation-in situ silylation
摘要:
Lithiation-in situ silylation of simple terminal epoxides using lithium 2,2,6,6-tetramethylpiperidide in combination with trimethylsilyl chloride provides a direct and experimentally convenient process for the synthesis of trans-alpha,beta-epoxysilanes.

molecules and often are used as intermediates in organic synthesis. Many alkenes exist in two stereoisomeric forms (E and Z), which have different structures and different properties. The selective formation of the two isomers is an important synthetic goal that has long inspired the development of new synthetic methods. However, the efficient synthesis of diastereopure, thermodynamically less stable, Z-alkenes

This manuscript describes the first practical benzylic dehydrogenation of electron-deficient heteroarenes, including pyridines, pyrazines, pyrimidines, pyridazines, and triazines. This transformation allows for the efficient benzylic oxidation of heteroarenes to afford heterocyclic styrenes by the action of nickel catalysis paired with an unconventional bromothiophene oxidant.
