In order to determine the absolute configuration of urothion (1), the CD spectra of tri-4-chlorobenzoyl derivatives of 2-amino-6-[(3R)-3, 4-dihydroxybuty1]pteridin-4(3H)-one and its (3S) compound were compared with that of the tri-4-chlorobenzoyl derivative obtained from the natural product. R-Configuration was concluded for the secondary hydroxyl group on the side chain of 1, which is the same configuration as that of molybdopterin (2). This supports the view that 1 might be a urinary metabolite of 2.
