2-C-Methyl-D-ribono-1,4-lactone

2-C-甲基-D-核糖酸-1,4-内酯

2-C-Methyl-D-ribono-1,4-lactone is a ketose which is formed from the thermal rearrangement of d-xylose. It has been shown to be an acceptor for episulfide and an 1-deoxy-d-ribulose. 2-C-Methyl-D-ribono-1,4-lactone has been found to yield dimethylamine when heated with magnesium. This compound can be ion exchanged with calcium and magnesium. 2CMR was first synthesized by the reaction of L(+) lactic acid with dimethylamine in the presence of magnesium chloride. The product was purified by crystallization from water, yielding a white powder that melts at 230°C.
