Zy. Liu et al., USING A RIGID MOLECULE TRICYCLODECADIENONE FOR THE STEREOSPECIFIC SYNTHESIS OF THE CHAIN COMPOUND SENECIVERNIC ACID, Journal of the Chemical Society. Perkin transactions. I (Print), (14), 1998, pp. 2127-2129
The highly efficient synthesis of a chain compound, senecivernic acid
2, using a rigid molecule, tricyclodecadienone 1, as the starting mate
rial via a retro-Diels-Alder reaction as the key step and without usin
g any protecting groups is described in a total of ten steps and in 50
% overall yield.
