(1S)-1,2-O-Benzyl­idene-α-d-glucurono-6,3-lactone

X-ray crystallographic analysis has established that the major product from the protection of d-glucoronolactone with benzaldehyde is (1S)-1,2-O-benzyl­idene-α-d-glucurono-6,3-lactone, C(13)H(12)O(6), rather than the R epimer. The crystal structure exists as O—H⋯O hydrogen-bonded chains of mol­ecule...

Sumario:X-ray crystallographic analysis has established that the major product from the protection of d-glucoronolactone with benzaldehyde is (1S)-1,2-O-benzyl­idene-α-d-glucurono-6,3-lactone, C(13)H(12)O(6), rather than the R epimer. The crystal structure exists as O—H⋯O hydrogen-bonded chains of mol­ecules lying parallel to the a axis. The absolute configuration was determined by the use of d-glucuronolactone as the starting material.
