2,3-O-(S)-Benzyl­idene-2-C-methyl-d-ribono-1,4-lactone

The crystal structure of the title compound, C(13)H(14)O(5), establishes (i) the (S) – rather than (R) – configuration at the acetal carbon and (ii) that both the acetal and the lactone form five- rather than six-membered rings; the absolute configuration is determined by the use of 2-C-methyl-d-rib...

description The crystal structure of the title compound, C(13)H(14)O(5), establishes (i) the (S) – rather than (R) – configuration at the acetal carbon and (ii) that both the acetal and the lactone form five- rather than six-membered rings; the absolute configuration is determined by the use of 2-C-methyl-d-ribono-1,4-lactone as the starting material. The compound consists of hydrogen-bonded chains of mol­ecules running along the a axis; there are no unusual packing features. Only classical hydrogen bonding has been considered.
