ABSTRACT:
A novel process for the manufacture of quinone derivatives is described.
In this process a compound of the formula ##STR1## is reacted with a compound of the formula ##STR2## and the resulting compound of the formula ##STR3## is subjected to a retro-Diels-Alder reaction. The substituents R.sup.1, R.sup.2, R.sup.3 and R.sup.4 have the significance given in the description.
