An, Zhi-min published the artcileStructural changes of 2-keto-L-gulonic acid studied by NMR spectroscopy, Formula: C6H10O7, the publication is Bopuxue Zazhi (2014), 31(3), 407-414, database is CAplus.
2-Keto-L-gulonic acid (2-KLG) changes its mol. structure in many solvents at room temperature A five-membered intramol. ring structure can easily be formed by the 2,5-hemiacetal reaction after the opening of the carbonyl group in 2-KLG (-C=O) to form a O-C-O interlinkage. In this study, we showed that the 13C chem. shift of the carbonyl changed from δ200 towards high field to about δ96 after forming the intramol. ring. Two-dimensional HMBC experiments revealed that 2-keto-L-gulonic acid formed five-membered ring 2,5-hemiacetal derivatives in seven solvents, instead of six-membered 2,6-hemiacetal derivatives
