ortho-selective C–H halogenation methodology is reported herein. The highlight of the work is the highly selective C(sp2)–H functionalization of benzyl nitriles in the presence of activated C(sp3)–H bond, which results in good yields of the halogenated products with excellent regioselectivity. Along with benzyl nitriles, aryl Weinrebamides and anilides have been evaluated for the transformation using aprotic

To provide a diagnostic drug which binds specifically to an amyloid aggregate and/or an amyloid deposit, to thereby realize imaging and quantification of a disease caused by amyloid aggregation and/or deposition.
The invention provides a compound represented by formula (1):
(wherein X1 represents an optionally substituted bicyclic heterocyclic group;
X2 represents a hydrogen atom, a halogen atom, or a chelate-forming group;
ring A represents a benzene ring or a pyridine ring; and
ring B represents an optionally substituted 5-membered aromatic heterocyclic group which is bonded to the benzene ring or the pyridine ring via a carbon atom of ring B), a salt thereof, a solvate of any of these, or a transition metal coordination compound of any of these, and a diagnostic, preventive, or therapeutic drug containing the same.
Disclosed in the present invention are a nitrogenous macrocyclic compound, a preparation method therefor, a pharmaceutical composition and an application thereof. The present invention provides a nitrogenous macrocyclic compound represented by formula III-0, a tautomer thereof, an optical isomer thereof, a hydrate thereof, a solvate thereof, a pharmacologically acceptable salt thereof, or a prodrug thereof. The compound can be effectively bond with bromodomains of a BET family: BRD4, BRD3, BRD2, and BRDT, so as to adjust transcription of a downstream gene c-myc and a related target gene thereof, and futher to adjust a downstream signal path and play a particular role, comprising treating diseases such as inflammatory diseases, cancers, and AIDS.
