摘要

A 2, 2, 6-trisubstituted cyclohexadienone is a normal component of the reacting system undergoing the paru-Claisen redrrangement, as shown by the isolation of a characteristic Diels-Alder adduct. The constitution of the adduct has been proved by an independent synthesis of its tetrahydro derivative In the case of 2, 4, 6-trimethylphenyl allyl ether, where no rearranged p-allylphenol is possible, a remarkably high yield of the dienone-maleic ...
