The present invention relates to a new process for the diastereoselective preparation of (1R*,4R*,5S*,6S*)-6-hydroxy-5-arylbicyclo[2.2.2]octan-2-one compounds, the compounds of the formula (II), which may subsequently be further transformed to 5-aryl-bicyclo[2.2.2]oct-5-en-2-one compounds of the formula (I):
The present invention further relates to novel (1R*,2S*,3S*,4R*)-6-oxo-3-arylbicyclo[2.2.2]octan-2-yl methanesulfonate compounds as such, which compounds are useful intermediates in the preparation of 5-aryl-bicyclo[2.2.2]oct-5-en-2-one compounds of the formula (I).
本发明涉及一种新的过程,用于选择性地制备(1R*,4R*,5S*,6S*)-6-羟基-5-芳基双环[2.2.2]辛-2-酮化合物,即式(II)的化合物,该化合物随后可以进一步转化为式(I)的5-芳基双环[2.2.2]辛-5-烯-2-酮化合物:本发明还涉及新型(1R*,2S*,3S*,4R*)-6-氧代-3-芳基双环[2.2.2]辛-2-基甲磺酸酯化合物,这些化合物本身就是有用的中间体,用于制备式(I)的5-芳基双环[2.2.2]辛-5-烯-2-酮化合物。
