Synthesis and crystal structure analysis of substituted bicyclo[3.3.1]nonanones
A set of novel bi-cyclo-[3.3.1]nona-nones, namely, 4-methoxybi-cyclo-[3.3.1]non-3-ene-2,9-dione, C<sub>10</sub>H<sub>12</sub>O<sub>3</sub> (<b>1</b>), 4,9,9-tri-methoxybi-cyclo-[3.3.1]non-3-en-2-ol, C<sub>12</sub>H<sub>20</sub>O<sub>4</sub> (<b>2</b>), 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, C<sub>22</sub>H<sub>32</sub>O<sub>3</sub> (<b>3</b>) and 4-(<i>tert</i>-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, C<sub>26</sub>H<sub>42</sub>O<sub>3</sub> (<b>4</b>), were synthesized and structurally elucidated by NMR, HRMS and X-ray crystallography.
