Tisdale, Eric J.,Chowdhury, Chinmay,Vong, Binh G.,Li, Hongmei,Theodorakis, Emmanuel A.
, p. 909 - 912 (2002)
(equation presented) Two different routes to the tricyclic core of Garcinia-derived natural products are described. The first approach is based on a tandem Claisen/ Diels-Alder rearrangement and delivers the desired lactone 14. The second approach, employ

Brown, Philip E.,Lewis, Robert A.,Waring, Mark A.
, p. 2979 - 2988 (2007/10/02)
Syntheses of 2,2-dimethylchromene-5,8-quinone, 2,2-dimethylchromene-6,7-quinone, and 6,7-dimethoxy-2,2-dimethylchromene-5,8-quinone are described.Being easily bioreductible to electron-rich chromenes these compounds, and their oxirane derivatives, are of
