BINAP/AgOTf/KF/18-crown-6 as new bifunctional catalysts for asymmetric Sakurai-Hosomi allylation and Mukaiyama aldol reaction
A catalytic amount of KF·18-crown-6 complex is effective as a soluble fluoride source to activate an asymmetric Sakurai-Hosomi allylation with BINAP and silver(I) triflate catalyst. The allylation of a variety of aromatic, α,β-unsaturated and aliphatic al
Chiral base-catalyzed aldol reaction of trimethoxysilyl enol ethers: Effect of water as an additive on stereoselectivities
An aldol reaction of trimethoxysilyl enol ether catalyzed by lithium binaphtholate is described. The aldol reaction of trimethoxysilyl enol ether derived from cyclohexanone under anhydrous conditions predominantly afforded the anti-aldol adduct with moder
Enantioselective aldol reaction of trimethoxysilyl enol ethers with aldehydes catalyzed by p-Tol-BINAP·AgF complex
New catalytic asymmetric Mukaiyama-type aldol reaction using trimethoxysilyl enol ethers was achieved using p-Tol-BINAP·AgF complex as a catalyst. High syn- and enantioselectivities were obtained both from the E- and Z-silyl enol ethers.
