A Diels–Alder reaction between cyclopentadiene and 3-O-acetyl-5,6-dideoxy-1,2-O-isopropylidene-6-nitro-α-D-xylo-hex-5-enose (3) gave a crystalline adduct, whose structure has been established to be that of 5-endo-nitro-6-exo-(3′-O-acetyl-1′,2′-O-isopropylidene-α-D-xylo-tetrofuranos-4′-yl)-2-norbornene (4) by nuclear magnetic resonance spectroscopy.
