    The tautomeric compositions of D-erythro-2-pentulose (D-ribulose) and D-threo-2-pentulose (D-xylulose) in aqueous solution have been studied by 13C-n.m.r. spectroscopy at various temperatures using 2-13C-substituted compounds. The alpha-furanose, beta-furanose, and acyclic carbonyl (keto) forms were detected at all temperatures, whereas the acyclic hydrate (gem-diol) form was not observed. The percentage of keto form increased with increasing temperature, at the expense of the furanose forms. Thermodynamic (delta G0, delta H0, delta S0) and kinetic parameters for the interconversion of alpha- and beta-furanoses with the acyclic carbonyl form were determined and compared with those determined under similar conditions for the structurally-related aldotetrofuranoses. The ring-opening rate constant (kopen) measured by 13C saturation-transfer n.m.r. spectroscopy in 50mM sodium acetate (pH 4.0) at 55 degrees were as follows: beta-threofuranose (0.65 s-1) greater than alpha-erythrofuranose (0.51 s-1) greater than beta-erythrofuranose (0.37 s-1) approximately beta-threo-2-pentulofuranose (0.35 s-1) greater than alpha-threofuranose (0.25 s-1) greater than alpha-threo-2-pentulofuranose (0.20 s-1) approximately alpha-erythro-2-pentulofuranose (0.18 s-1) approximately beta-erythro-2-pentulofuranose (0.18 s-1). Within each structural type the pentulofuranose anomer having O-2 and O-3 cis (O-1 and O-2 cis in aldotetrofuranoses) opens faster than, or at a similar rate to, the alternative anomer having these oxygen atoms trans. Ring-closing rate constants (kclose), calculated from kopen and Keq, decrease in the order beta-erythrofuranose (15 s-1) greater than beta-threofuranose (12 s-1) greater than alpha-erythrofuranose (9.9 s-1) greater than alpha-threofuranose (6.2 s-1) greater than beta-threo-2-pentulofuranose (0.71 s-1) greater than alpha-erythro-2-pentulofuranose (0.38 s-1) greater than alpha-threo-2-pentulofuranose (0.13 s-1) approximately beta-erythro-2-pentulofuranose (0.13 s-1). Replacement of H-1 in aldotetrofuranoses by a hydroxymethyl group (i.e., conversion to 2-pentuloses) significantly decreases the ring-opening and ring-closing rate constants of furanose anomerization.
