A radical mediated approach to the core structure of huperzine A
Ward, Jarrod,Caprio, Vittorio
, p. 553 - 556 (2006)
The synthesis of the core structure of huperzine A by cyclisation of 2-pyridylmethyl radicals is described. (2-Methylpyridin-3-yl)cyclohexenols are directly selenated at the benzylic position by deprotonation/selenation and the products undergo either 5-e
