Copper-catalyzed one-pot oxidation-aldol/henry reaction of benzylic amines to α,β-unsaturated methyl ketone/nitro compounds
A novel one-pot synthesis of α,β-unsaturated methyl ketone/nitro compounds from benzylic amines through an oxidation-aldol/Henry reaction is reported. The reaction proceeded well by using MCPBA as oxidant and CuCl 2·2H2O as catalyst. A variety of functionalized α,β-unsaturated methyl ketone/nitro compounds were assembled in moderate yields by application of this catalytic one-pot reaction. Georg Thieme Verlag Stuttgart New York.
