Abstract:
A set of novel bi-cyclo-[3.3.1]nona-nones, namely, 4-methoxybi-cyclo-[3.3.1]non-3-ene-2,9-dione, C10H12O3 (1), 4,9,9-tri-methoxybi-cyclo-[3.3.1]non-3-en-2-ol, C12H20O4 (2), 4-meth-oxy-6-methyl-1-(3-methyl-but-2-en-1-yl)-6-(4-methyl-pent-3-en-1-yl)bi-cyclo-[3.3.1]non-3-ene-2,9-dione, C22H32O3 (3) and 4-(tert-but-yl)-4-hy-droxy-2-meth-oxy-8-methyl-7-(3-methyl-but-2-en-1-yl)-8-(4-methyl-pent-3-en-1-yl)bi-cyclo-[3.3.1]non-2-en-9-one, C26H42O3 (4), were synthesized and structurally elucidated by NMR, HRMS and X-ray crystallography.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
