A Ruthenium-Catalyzed, Atom-Economical Synthesis of Nitrogen Heterocycles
摘要:
The Ruthenium catalyzed, atom-economical domino redox isomerization/cyclization of tethered aminopropargyl alcohols is reported. This process displays a broad scope and functional group tolerance, Furthermore, it presents a novel retrosynthetic disconnection linking simple and easily available, linear propargyl alcohols with added-value nitrogen heterocycles in a single catalytic step.[GRAPHICS]

Expedient Synthesis of <i>C</i><sub>3</sub>-Symmetric Hexasubstituted Benzenes via Nicholas Reaction/[2 + 2 + 2] Cycloaddition. New Platforms for Molecular Recognition
reaction from the starting dicobalt hexacarbonyl–propargylic complex. The macrocycles obtained were modified through [2 + 2 + 2] cycloaddition, generating two new C3-symmetric hexasubstituted benzene structures suitable for molecular recognition purposes.
