1,4a-Dimethyl-6-methyl­ene-5-(5,5,6,6-tetra­cyano-2-methyl­cyclo­hex-2-enylmeth­yl)deca­hydro­naphthalene-1-carboxylic acid: a trans-communic acid derivative

In the search for cancer chemopreventive agents, we have studied the Diels–Alder reaction of trans-communic acid with tetra­cyano­ethyl­ene in the presence of SiO(2) as catalyst. The title cycloadduct, C(26)H(30)N(4)O(2), was obtained in 75% yield. The mol­ecules are arranged in pairs through O—H⋯O...

Descripción
Sumario:In the search for cancer chemopreventive agents, we have studied the Diels–Alder reaction of trans-communic acid with tetra­cyano­ethyl­ene in the presence of SiO(2) as catalyst. The title cycloadduct, C(26)H(30)N(4)O(2), was obtained in 75% yield. The mol­ecules are arranged in pairs through O—H⋯O hydrogen bonds, forming an R (2) (2)(8) ring motif. Both the fused cyclohexyl rings adopt a chair conformation, whereas the nonfused ring adopts a half-chair conformation.
