Synthesis of an Electrophilic Keto-Tetraene 15-oxo-Lipoxin A4 Methyl Ester via a MIDA Boronate.


ABSTRACT: 15-oxo-Lipoxin A4 (15-oxo- LXA4) has been identified as a natural metabolite of the fatty acid signaling mediator Lipoxin A4. Herein, we report a total synthesis of the methyl ester of 15-oxo-LXA4 to be used in investigations of potential electrophilic bioactivity of this metabolite. The methyl ester of 15-oxo-LXA4 was synthesized in a convergent 15 step (9 steps longest linear) sequence starting from 1-octyn-3-ol and 2-deoxy-D-ribose with Sonogashira and Suzuki cross-couplings of a MIDA boronate as key steps.
