Synthesis of pterocellin A
O'Malley, Meaghan M.,Damkaci, Fehmi,Kelly, T. Ross
, p. 2651 - 2652 (2006)
The first total synthesis of pterocellin A (1) was achieved in 10 linear steps from commercially available kojic acid (6) and 2-bromo-3-pyridinol (11) in a convergent sequence. The key constructive steps are a directed lithiation to couple two pyridines a
