Ruthenium-Catalyzed [2 + 2 + 2] Cycloaddition Reaction Forming 2‑Aminopyridine Derivatives from α,ω-Diynes and Cyanamides
A novel, efficient,
and mild synthetic route for the preparation
of 2-aminopyridines via ruthenium-mediated [2 + 2 + 2] cycloaddition
of α,ω-diynes and cyanamides has been developed. This
atom-economical catalytic process demonstrated remarkable regioselectivities
to access pyridine derivatives of high synthetic utility
Access toward Fluorenone Derivatives through Solvent-Free Ruthenium Trichloride Mediated [2 + 2 + 2] Cycloadditions
An efficient and
practical route for the preparation of highly
substituted fluorenones and analogues via solvent-free ruthenium trichloride
mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and alkynes
has been developed. This green chemistry approach involves a solventless
and atom-economical catalytic process to generate densely functionalized
fluorenones and related derivatives of high synthetic utility
Synthesis of Fluorescent Azafluorenones and Derivatives via a Ruthenium-Catalyzed [2 + 2 + 2] Cycloaddition
An original and mild
synthetic route for the preparation of novel azafluorenones and derivatives
via a ruthenium-mediated [2 + 2 + 2] cycloaddition of α,ω-diynes
and cyanamides has been developed. This atom-economical catalytic
process demonstrated remarkable regioselectivities to access fluorescent
azafluorenone derivatives. The photophysical properties of azafluorenone
derivatives have been evaluated, and photoluminescence phenomena at
solid and liquid states have been highlighted
