A. Sakurai et al., STUDIES ON UROTHION - SYNTHESIS OF (R)-DEPHOSPHO FORM-B, A DEGRADATION PRODUCT OF THE MOLYBDENUM COFACTOR, Heterocyclic communications, 2(4), 1996, pp. 383-386
In order to determine the absolute configuration of the dephospho Form
-B (3b) derived from urothion (4), 1,2-dihydroxyethyl]thieno[3,2-g]pte
ridin-5(6H)-one ((R)-3b) and its (1S)-enantiomer ((S)-3b) were synthes
ized. Comparing their CD spectra with that of 3b, the R-configuration
was concluded for the secondary hydroxyl group on the side chain of 3b
, as well as 4.
