The present application relates to novel fused, heteroatom-bridged pyrazole and imidazole derivatives, to processes for their preparation, to their use, alone or in combination, for the treatment and/or prevention of diseases and to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of cardiovascular disorders.
Two visible-light mediated protocols (based on a copper photoredox catalyzed and on a photochemical reaction, respectively) for the preparation of aryl thiocyanates and aryl selenocyanates from arylazo sulfones are presented herein, by exploiting the peculiar photoreactivity and redox activity of such substrates. The developed reactions take place in good to satisfactory yields and with a large scope
Nitromethane has been developed to be an effective cyanating reagent for the synthesis of thiocyanates. In the presence of iodine and base, a wide range of disulfides were reacted with nitromethane smoothly to give diverse thiocyanates in moderate to good yields. (C) 2015 Elsevier Ltd.
