Catalytic Asymmetric Alkylation of Aldehydes by Using Trialkylboranes
Triethylborane can be used in the asymmetric alkylation of aldehydes by using a 3‐(3,5‐diphenylphenyl)‐H8‐BINOL‐derived titanium(IV) catalyst in the presence of an excess amount of titanium tetraisopropoxide. The reaction proceeds with a low catalyst loading (2 mol‐%), exhibiting high enantioselecti...

| description | Triethylborane can be used in the asymmetric alkylation of aldehydes by using a 3‐(3,5‐diphenylphenyl)‐H8‐BINOL‐derived titanium(IV) catalyst in the presence of an excess amount of titanium tetraisopropoxide. The reaction proceeds with a low catalyst loading (2 mol‐%), exhibiting high enantioselectivity for aromatic and unsaturated aldehydes. (© Wiley‐VCH Verlag GmbH & Co.
