Abstract: | X-Ray crystallographic analysis was performed on the compound to which had been assigned the structure of 1,2,3-tri-O-acetyl-4,5-dideoxy-4-C-[(R)-phenylphosphinyl]-α--lyxofuranose. The results showed that the compound has the proposed configuration, the five-membered ring is in the E3 conformation, with a tendency towards the 3T2 form, the substituents at P-5 and C-5 are linked bisectionally, the acetoxyl group at C-2 and the methyl group at C-4 are linked quasiequatorially, and the acetoxyl group at C-3 is linked axially. |
