Synthesis and properties of a lipid bilirubin analog
Thyrann, Thomas,Lightner, David A.
, p. 447 - 460 (2007/10/03)
A new synthesis of dipyrrinone acids is described from the known dipyrrinone, 3-ethyl-2,7,9-trimethyl-(10H)-dipyrrin-1-one (11) with a free β-position. In six steps, 11 was converted to 5 with a C20 eicosanoic acid chain, and 5 was converted to
