In the presence of Eu(fod)3, (1E)-(2′,3′,4′,6′-tetra-O-acetyl-β-d-glucopyranosyloxy)buta-1,3-diene and its (3Z)-4-O-acetyl derivative undergo Re-face and endo selective hetero Diels-Alder reactions with 4-nitrobenzaldehyde, 5-nitrofuran-2-carbaldehyde and 5-nitrothiophene-2-carbaldehyde. The cycloadducts are converted into the title compounds, early examples of ‘free’ 5-C-arylpentopyranoses.
