The Structures of the Trihydroxyflavans from the Acid-catalyzed Rearrangement and Dimerization of 3-Carene-2,5-dione

The structures of the trimethyl ethers of three of the four mechanistically probable trihydroxyflavans derived by acid-catalyzed rearrangement and dimerization of 3-carene-2,5-dione have been assig...
