Cycloaddition-based Formal C–H Alkynylation of Isoindoles Leading to the Synthesis of Air-stable Fluorescent 1,3-Dialkynylisoindoles
摘要:
Reaction of N-alkylisoindoles with (bromoethynyl)triisopropylsilane afforded 1,3-bis(triisopropylsilylethynyl) isoindoles in high yields. The formal C-H alkynylation proceeds under transition-metal-free conditions through [4 + 2] cycloaddition of the pyrrole ring of isoindole with bromoalkyne followed by ring-opening of the product.

Integrated Catalytic C−H Transformations for One-Pot Synthesis of 1-Arylisoindoles from Isoindolines via Palladium-Catalyzed Dehydrogenation Followed by C−H Arylation
A one-pot conversion of isoindolines to 1-arylisoindoles was established from palladium-catalyzed cascade C−H transformations, that is, the dehydrogenation of isoindolines to give isoindoles, with subsequent C−H arylation of the isoindoles.
The application relates to 2-amino-4-(substituted amino)phenyl carbamate derivatives, or pharmaceutically acceptable salts or solvates thereof, as KCNQ2/3 potassium channel modulators, and methods of their uses.
