Rb. Bates et al., THERMAL REARRANGEMENT OF THE DIELS-ALDER DIMER OF 2,6-DIMETHYL-6-HYDROXYCYCIOHEXA-2,4-DIENONE TO A PENTACYCLIC DIMER, Tetrahedron letters, 38(14), 1997, pp. 2405-2408
In the absence of a reactive alkene, the Diels-Alder dimer of 2,6-dime
thyl-6-hydroxycyclohexa-2,4-dienone rearranges at 160 degrees C to a n
ew dimer via a reverse Diels-Alder reaction, two alpha-hydroxyketone r
earrangements, two Michael additions, and two aldol condensations. (C)
