A Diels–Alder reaction-based strategy for the synthesis of indoles and related heterocycles is reported. An intramolecular cycloaddition of alkyne-tethered 3-aminopyrones gives 4-substituted indolines in good yield and with complete regioselectivity. Additional substitution is readily tolerated in the transformation, allowing synthesis of complex and non-canonical substitution patterns. Oxidative conditions give the corresponding indoles. The strategy also allows the synthesis of carbazoles. The method was showcased in a formal synthesis of lysergic acid.
Intramolecular Remote C-H Activation via Sequential 1,4-Palladium Migration to Access Fused Polycycles

An unprecedented intramolecular remote C-H activation via sequential 1,4-palladium migration with an aromatic ring as a conveyor has been described. This reaction provides an efficient route to construct diverse polycyclic frameworks in moderate to good yield via palladium-catalyzed remote C-H activation/alkene insertion, arylation, alkenylation, and the Heck reaction. The preliminary mechanistic studies revealed that the 1,4-palladium migration process was reversible.

A novel compound in which a delayed fluorescence component due to TTA accounts for a high proportion of emissive components is provided. The organic compound includes an anthracene skeleton, an arylene group, and a substituted or unsubstituted heterocyclic group including a carbazole skeleton. The anthracene skeleton and the substituted or unsubstituted heterocyclic group including the carbazole skeleton are bonded to each other through the arylene group. The anthracene skeleton includes an aryl group at the 2-position or the 3-position.

One-pot synthesis: An efficient amino-directed one-pot synthesis of N-H carbazoles from unprotected 2-aminobiaryl compounds is reported. The free amino unit acts as both a directing group for ortho C-H activation and a functional group for construction of an N-heterocyclic ring (see scheme). Copyright
