内容記述
The scope of the copper-catalyzed coupling reactions between organoboron compounds and allylic phosphates is expanded significantly by employing triphenylphosphine as a ligand for copper, allowing the use of secondary alkylboron compounds. The reaction proceeds with complete gamma-E-selectivity and preferential 1,3-syn stereoselectivity. The reaction of gamma-silicon-substituted allylic phosphates affords enantioenriched alpha-stereogenic allylsilanes.
