| | D(+)-Ribonic acid gamma-lactone Usage And Synthesis |
| Chemical Properties | White Crystalline Solid | | Uses | A sugar lactone as inhibitor of β-galactosidase of E. coli. | | Uses | Important chiral synthon | | Uses | D-ribono-1,4-lactone is a compound useful in organic synthesis. | | Definition | ChEBI: A five-membered form of ribonolactone having D-configuration. | | Purification Methods | Purify D-(+)-ribonic acid--lactone by recrystallisation from EtOAc. The tribenzoate has m 54-56o (from AcOH), [] D 25 +27o (c 2.37, Me2NCHO), and the 3,5-O-benzylidene derivative has m 230-231.5o (needles from Me2CO-pet ether) and [] D 25 -177o (CHCl3).
