The present application relates to novel substituted aryl compounds, processes for their preparation, their use for treatment and/or prevention of diseases and their use for the preparation of medicaments for treatment and/or prevention of diseases, in particular for treatment and/or prevention of hyperproliferative and angiogenic diseases and those diseases which arise from metabolic adaptation to hypoxic states. Such treatments can be carried out as monotherapy or also in combination with other medicaments or further therapeutic measures.
A compound represented by the formula (I):
wherein each symbol is as described in the SPECIFICATION, or a salt thereof has a PDE2A inhibitory action, and is useful as a prophylactic or therapeutic drug for schizophrenia, Alzheimer's disease and the like.
of phenylglycinol derivatives with terminal and internalalkynes directed by picolinamide auxiliary has been developed. This method offers an efficient and highly regioselective route for the synthesis of 1-hydroxymethyltetrahydroisoquinolines. The reaction employs commercially available Co(II) catalyst in the presence of Mn(III) cooxidant and oxygen as a terminal oxidant, and proceeds with full preservation
An efficient method for the synthesis of 3-hydroxymethyl isoindolinones via cobalt-catalyzed C(sp2)–H carbonylation of phenylglycinol derivatives using picolinamide as a traceless directing group is demonstrated. The reaction proceeds in the presence of a commercially available cobalt(II) tetramethylheptanedionate catalyst and employs DIAD as a “CO” surrogate. This synthetic route offers a broad substrate
