The First Optically Active and Sterically Regular Poly(1,1‘-bi-2-naphthol)s:  Precursors to a New Generation of Polymeric Catalysts

Synthesis of chiral conjugated propeller-like polymers using optically active 1,1′-binaphthyl-2,2′-diamine derivatives

“…Applications of these compounds in asymmetric synthesis and chiral recognition have been extensively studied [1][2][3] . Recently, we have also used the optically active 1 as the starting material to build a class of chiral conjugated polymers for materials application [4][5][6][7][8][9][10] as well as for asymmetric catalysis [11][12][13][14][15] . Among these materials, (R)-2 represents a structurally very interesting polymer ( Fig.…”

Asymmetric Catalysis with Helical Polymers

“…This initiator was made by treating a mixture of (S)-or (R)-1-(2-pyrrolidinomethyl)pyrrolidine (25) and N,N'-diphenylethylenediamine (26) with one equivalent of nBuLi (Scheme 8). This forms a chiral base complex, which is able to initiate the helix-sense-selective anionic polymerization.…”

Synthesis of Wholly Aromatic Polyketones Containing Optically Active Macrocycles

“…[1][2][3] Binaphthyl-containing polymers such as polyarylenes, polyimides, and polycarbonates have been much reported, which have been applied to polymeric catalysts and so on. [4][5][6][7][8] We have also reported the syntheses of optically active aromatic polyketones bearing 2,2 0 -dioxy-1,1 0 -binaphthyl-6,6 0 -diyl units via nucleophilic aromatic substitution polymerization and nickel complex-mediated aromatic coupling polymerization. [9][10][11] The resulting polyketones have high thermal stability and excellent solubility to organic solvents such as CHCl 3 and DMF.…”
