N2 - The conformations of d-pentono-1,4-lactones in solution were studied by 1H- and 13C-n.m.r. spectroscopy. Conformational equilibria between the 3E and E3 forms were found to favor, strongly, that having the OH-2 group quasiequatorially oriented. The exocyclic, CH2OH groups in these lactones generally favor the gauche-gauche disposition around the C-4C-5 bond, except for d-lyxono-1,4-lactone, which favors the trans-gauche arrangement.
