Cascade Alkenylation/Intramolecular Friedel-Crafts Alkylation: High Selectivity at the C7-Position of BINOL

Hao Liu et al.

Summary: A cost-effective Co(III)-catalyzed C-H cascade alkenylation/intramolecular Friedel-Crafts alkylation reaction has been developed for the efficient synthesis of C7 site-selective BINOL derivatives. With the aid of a pyrazole directing group, this protocol allows the rapid synthesis of various BINOL-tethered spiro[cyclobutane-1,1'-indenes] compounds.

Selective Synthesis of Bis-Heterocycles via Mono- and Di-Selenylation of Pyrazoles and Other Heteroarenes

Jaspreet Kour et al.

Summary: The insertion of selenium in the form of mono-selenides and di-selenides was used for the preparation of novel bis-heterocyclic compounds. This method is more general and provides a diverse scaffold with high product yields. The selectivity of the mono- and di-selenylation reactions, which is dependent on concentration, was achieved using SeO2 as an effective selenylating reagent.

Ru-Catalyzed Selective C-H Functionalization of Pyridotriazoles with Acrylates

Abhisek Joshi et al.

Summary: This study describes the ruthenium-catalyzed efficient and selective C-H alkenylation of pyridotriazoles with acrylates, where the combination of metals (Ru and Fe) plays a crucial role in achieving quantitative yields of the desired products. The reaction is proposed to involve the formation of a ruthenium cyclometalated intermediate.
