Total Synthesis of Junipegenin-A, an Isoflavone from Juniperus macropoda

Junipegenin-A (1), a new isoflavone isolated from Juniperus macropoda has been synthesised in nine steps, starting from gallic acid.The key step is the oxidative rearrangement of the intermediate benzyloxychalkone (9) by thallium(III) nitrate to give acetal (10) followed by cyclisation to the corresponding isoflavone (1), identical (m.m.p., co-TLC and co-IR) with a natural sample.
