Synthesis of 10,11-Dihydro-12-oxo-LTB4, a Key Biochemical Intermediate

Abstract
The first total synthesis of the 5(S)-hydroxy-10,11-dihydro-12-oxo-6(Z),8(E),14(Z)-eicosatrienoic acid (10,11-dihydro-12-oxo-LTB(4)) (3) is reported. This compound is a key pivotal intermediate in the biotransformation of LTB(4) by the so-called "LTB(4) reductase pathway".
