Trimethylsilyl methylenenitronate reacts with both aliphatic and aromatic aldehydes in the presence of catalytic amounts of scandium(III) triflate to form the Henry reaction products in low (25%) to good yields (77%). This is the first example of this silyl nitronate undergoing a nitro-aldol reaction under an acid environment.
