Abstract
The reduction of mesobiliverdin XIII alpha propan-1,3-diyl diester wit h NaBH4 affords mesobilirubin XIII alpha propan-1,3-diyl diester. The same reduction of mesobiliverdin XIII alpha methylen diester. The same reduction of mesobiliverdin XIII alpha methylen diester affords ropyl )-2,7,13,17-tetramethylbiladien-ac-1,19-(21H, 24H)-dione (MBR-mc). The UV/Vis and H-1 NMR spectra of MBR-mc show that its structure in solut ion is similar to that of the natural bilirubins of the a series.
