7,7-Dimethyl-3,3,4a-tris­(3-methyl­but-2-en­yl)-4a,5,6,7-tetra­hydro-2H-chromene-2,4(3H)-dione

The title compound, C(26)H(38)O(3), was prepared by an intra­molecular Claisen-like cyclization of ethyl 2-acet­oxy-4,4-dimethyl-1-(3-methyl­but-2-en­yl)cyclo­hex-2-enecarboxyl­ate followed by dialkyl­ation. One of the methyl groups is disordered over two sets of sites in a 0.67:0.33 ratio.
