Synthesis of Carbolines by Photostimulated Cyclization of Anilinohalopyridines
摘要:
A general synthetic route to prepare all four carboline regioisomers by photo stimulated cyclization of anilinohalopyridines is described. The methodology affords various substituted carbolines in good to excellent yields. In the case of alpha-carbolines, the S(RN)1 methodology complements previously reported palladium-catalyzed cyclization approaches.
An efficient strategy for the intramolecular denitrogenative transannulation/C(sp2)-H amination of 1,2,3,4-tetrazoles bearing C8-substituted arenes, heteroarenes, and alkenes is described. The process involves the generation of the metal-nitrene intermediate from tetrazole by the combination of [Cp*IrCl2]2 and AgSbF6. It has been shown that the reaction proceeds via an unprecedented electrocyclization

To provide methods for preparing alpha-carboline derivatives in few steps, as well as conveniently and industrially advantageously. A method for preparation of a compound represented by Formula (II) or a salt thereof, comprising subjecting a compound represented by Formula (I) or a salt thereof to a ring closure reaction in the presence of a palladium catalyst, a ligand, and a base; a method for preparation of a compound represented by Formula (IX) or a salt thereof, comprising subjecting a compound represented by Formula (VII) or a salt thereof to a ring closure reaction in the presence of a palladium catalyst, a ligand, and a base, and subsequently to an aromatization reaction; and methods for preparation of compounds represented by Formulae (XV), (XVII), and (XIX) or a salt thereof, comprising subjecting respective compounds represented by Formulae (II) and (IX) or a salt thereof to a reaction for introducing a leaving group when necessary, and subsequently to a coupling reaction: wherein the symbols respectively represent the same meaning as defined in the present specification.
