Regioselective and stereoselective C−O activation was achieved for atroposelective synthesis of N-arylisoquinoline-1,3(2H,4H)-diones. This method set up a new synthetic strategy for C−N atropisomersynthesis via an enantioselective ring-opening dynamic kinetic resolution process.
N-芳基异喹啉-1,3(2 H ,4 H )-二酮的空间选择性合成实现了区域选择性和立体选择性 C−O 活化。该方法通过对映选择性开环动态动力学拆分过程,建立了 C−N 阻转异构体合成的新合成策略。

The refinement of our original five point pharmacophore model for the H(3) receptor with the addition of a new acceptor feature is presented. The importance of this new acceptor feature for the binding and the selectivity against H(1), H(2) and H(4) has been validated using a newly synthesized naphthalene series. With the SAR deduced from several hundred naphthalene derivatives in various sub-classes the specific role of each pharmacophoric feature, by varying the geometry, size and charge of the molecules, was elucidated. This led to the discovery of a highly potent and selective new compounds series. (c) 2008 Elsevier Ltd. All rights reserved.
