The present invention relates to new compounds of formula (I), wherein Q is a partially saturated ring or Nl-oxides, salts, solvates or solvated salts thereof, processes for their preparation and new intermediates used in the preparation thereof and to the use of said compounds as metabotropic glutamate receptors ligands in therapy.
Regio- and diastereoselective synthesis of (3,4,8,9)-dibenzo-2,7-dioxa-5,10-diaza[4.4.4] propellanes from 4-substituted 1,2-cyclohexanediones and o-aminophenols, a computational approach to regioselectivity prediction

The regio- and diastereoselective condensation reactions between 4-Me and 4-t-Bu substituted 1,2-cyclohexanediones and substituted o-aminophenols yielding the [4.4.4] propellane derivatives have been studied. The possibility of using semi-empirical PM3 calculations for rationalization and prediction of the regioisomer formation has been studied.
研究了4-Me和4- t -Bu取代的1,2-环己二酮与取代的邻氨基苯酚之间的区域和非对映选择性缩合反应,生成[4.4.4]丙炔衍生物。研究了使用半经验PM3计算进行区域异构体形成的合理化和预测的可能性。
