    A new class of bifunctional chiral phase transfer catalysts for highly enantioselective asymmetric epoxidation of α,β-unsaturated ketones at ambient temperature
    摘要:
    A new type of bis-quaternary ammonium bromide as chiral multifunctional phase transfer catalysts derived from readily available inexpensive cinchona alkaloids has been developed and evaluated for the enantioselective asymmetric epoxidation of various chalcones in the presence of lower concentrations of various oxidants, bases, solvents and ambient temperature conditions. Under optimized reaction conditions, highest chemical yields of up to 98% along with the excellent enantioselectivities of about 99% were obtained by using the cinchona based chiral multifunctional phase transfer catalysts.

  • N-Heterocyclic Carbene Catalyzed Oxidative Coupling of Alkenes/ α-Bromoacetophenones with Aldehydes: A Facile Entry to α,β-Epoxy Ketones
    作者:Rambabu N. Reddi、Pragati K. Prasad、Arumugam Sudalai

    日期:2015.11.16
    A novel, Nheterocyclic carbene (NHC) catalyzed direct oxidative coupling of styrenes with aldehydes has been described for the synthesis of α,β‐epoxy ketones in good yields. This unprecedented regioselective oxidative coupling employs NBS/DBU/DMSO (DBU=1,8‐diazabicyclo [5.4. 0] undec‐7‐ene, DMSO=dimethylsulfoxide, NBS=N‐bromosuccinimide) as an oxidative system at ambient conditions. Additionally,

  • 4-Substituted-α,α-diaryl-prolinols Improve the Enantioselective Catalytic Epoxidation of α,β-Enones
    作者:Yawen Li、Xinyuan Liu、Yingquan Yang、Gang Zhao
    DOI:10.1021/jo0617619
    日期:2007.1.1
    To seek novel metal-free organic catalysts for epoxidation with high stereoselectivity, a series of 4-substituted-α,α-diaryl-prolinols were synthesized in four steps from trans-4-hydroxyl-l-proline. These prolinol derivatives catalyzed the asymmetric epoxidation of α,β-enones to give the corresponding chiral epoxides in good yields and high enantioselectivities under mild reaction conditions.

    still a challenging task. In this perspective, we present the application of chiral dinuclear magnesium complexes for asymmetric epoxidation of a broad range of electron-deficient enones. We demonstrate that the in situ generated magnesium-ProPhenol complex affords enantioenriched oxiranes in high yields and with excellent enantioselectivities (up to 99% ee).

    使用更便宜且无毒的碱土属催化剂的不对称合成正成为主要依赖贵属的传统催化方法的重要且可持续的替代方法。尽管有一些可持续的烯酮对映选择性环氧化方法,但为这些反应开发基于配合物的明确且有效的催化剂仍然是一项具有挑战性的任务。从这个角度来看,我们展示了手性双核配合物在各种缺电子烯酮的不对称环氧化中的应用。我们证明,原位生成的-苯酚复合物以高产率和优异的对映选择性(高达 99% ee)提供富含对映体的环氧乙烷。我们的广泛研究验证了该领域的文献数据,并为更好地了解控制氧合过程的因素提供了一步。精心制作的催化剂提供温和的反应条件和真正广泛的底物范围。
