Processes for preparing 3-substituted phenylalkylamines comprising reacting a phenyl boronic compound with an α-β unsaturated carbonyl-containing compound via an asymmetric 1,4-addition reaction, followed by reductive alkylation. The processes may be useful in the synthesis of tapentadol.
The invention provides methods for preparing substituted phenylalkanes. In particular, the processes comprise reacting a phenyl boronic compound with an α-β unsaturated carbonyl-containing compound via an asymmetric 1,4-addition reaction. The processes may be useful in the synthesis of tapentadol.
