  Synthesis and structural characterization of a dichloro zinc complex of N,N′-bis-(2,6-dichloro-benzyl)-(R,R)-1,2-diaminocyclohexane: Application to ring opening polymerization of rac-lactide

  摘要：

  A novel dichloro zinc complex (L-1)ZnCl2, where L-1 is N,N'-bis-(2,6-dichloro-benzyl)-(R,R)-1,2-diaminocyclohexane, has been synthesized and characterized. The dimethyl derivatives, generated in situ from the well characterized dichloro zinc complexes (L-1)ZnCl2 and (L-2)ZnCl2, where L-2 is N,N'-bis-(benzyl)-(R,R)-1,2-diaminocyclohexane, were employed as initiators for the ring opening polymerization (ROP) of rac-lactide (rac-LA). The complexes were found to be highly efficient initiators yielding the polylactide (PLA) with a narrow molecular weight distribution. The catalytic activity and heterotactic selectivity of the Zn(II) complexes were affected by the substituents on the phenyl groups of benzyl moieties in (R,R)-1,2-diaminocyclohexane. The dimethyl derivative of (L-2)ZnCl2 produced highly stereocontrolled PLA with P-r = 0.75 at -25 degrees C. (C) 2011 Elsevier Ltd. All rights reserved.

  scrambling is observed in competitive carbenoid insertions into PhMe2Si-D/Ph2MeSi-H, indicating that the insertion reaction takes place in a concerted fashion. These results are discussed in light of an early transition state, characterized by hydrogen-first penetration of the Si−H bond into the copper−carbenoid cavity, which is assumed to impart high levels of enantioselectivity due to intrinsic preorganization

  A library of chiral zinc complexes formed in Situ by the combination of achiral and racemic diimines with 3,3'-di(3,5-ditrifluoromethylphenyl)-BINOL and diethylzinc were evaluated in the asymmetric addition of diethylzine to N-acylimines. In the presence of 10 mol % of chiral ligand 4 and racemic diimine 5, high enantioselectivities of up to 97% ee and yields of up to 96% were achieved for a wide range of aromatic imines in dichloromethane at -30 degrees C.

  The enantioselective Henry reaction was efficiently carried out under mild reaction conditions in 96% ethanol. The chiral C-2-symmetric, secondary bisamines based on the 1,2-diaminocyclohexane framework and copper(II) acetate were found to promote the asymmetric nitroaldol reaction. Aromatic and aliphatic aldehydes were reacted with nitromethane to provide the corresponding beta-nitroalcohols in very good yields and enantioselectivities up to 94%. (C) 2008 Elsevier Ltd.
