Synthesis of hemitectol, tectol, and tecomaquinone i

Cadelis, Melissa M.,Barker, David,Copp, Brent R.

, p. 2939 - 2942 (2012)

The first total syntheses of Tectona grandis (teak) natural products hemitectol and tectol are described. The observation of spontaneous dimerisation of hemitectol to tectol suggests the monomer is the true natural product and that the dimer is an artifact of isolation.
