Shibata, Takanori; Arai, Yoshikazu; Tahara, Yuki published the artcile< Enantioselective Construction of Quaternary Carbon Centers by Catalytic [2 + 2 + 2] Cycloaddition of 1,6-Enynes and Alkynes>, COA of Formula: C44H40P2, the main research area is bicyclic cyclohexadiene quaternary carbon stereocenter preparation; enyne alkyne enantioselective cycloaddition chiral rhodium catalysis.
The enantioselective [2 + 2 + 2] cycloaddition of 1,6-enynes and alkynes using chiral rhodium catalysts gave cycloadducts containing quaternary carbon stereocenters. Both sym. and unsym. alkynes and acetylene could be used as coupling partners, and the corresponding bicyclic cyclohexa-1,3-dienes were obtained in good to excellent ee.
Organic Letters published new progress about Alkenynes Role: RCT (Reactant), RACT (Reactant or Reagent). 139139-93-8 belongs to class chiral-phosphine-ligands, and the molecular formula is C44H40P2, COA of Formula: C44H40P2.
