    名称:
    Substrate modification to increase the enantioselectivity of hydrolases. A route to optically-active cyclic allylic alcohols.
    摘要:
    The esterase-catalyzed resolution of the cyclic allylic acetates - 1-acetyloxy-2-cyclopentene, 1-acetyloxy-2-cyclohexene, and 1-acetyloxy-2-cycloheptene - was not enantioselective. We hypothesized that this inefficiency stems from the similarity in size of the substituents at the stereocenter (CH2-CH2 vs. CH=CH). To increase the enantioselectivity, we resolved precursors to these cyclic allylic alcohols: esters of trans-2-bromocycloalkanols (C5, C6, C7). These esters had a larger difference in the size of the substituents (CH2 vs. CHBr) at the stereocenter and were efficiently resolved by both cholesterol esterase and lipase from Pseudomonas cepacia (Amano P, PCL). A synthetic-scale resolution with PCL yielded the (1S,2S)-1-butanoyloxy-2-bromocycloalkanes in >98% ee. Heating with DBU to eliminate HBr, followed by reduction with LiAlH4 to cleave the ester, yielded the allylic alcohols: (S)-(-)-2-cyclopenten-1-ol (65% ee), (S)-(-)-2-cyclohexen-1-ol (>99% ee), and (S)-(-)-2-cyclohepten-1-ol (>98% ee).

  • Metal(II)<i>d</i>-Tartrates Catalyzed Asymmetric Ring Opening of Oxiranes with Various Nucleophiles
    作者:Hiroyuki Yamashita
    DOI:10.1246/bcsj.61.1213
    日期:1988.4
    The asymmetric ring opening of meso-2,3-disubstituted oxiranes with thiols, aniline, and trimethylsilyl azide was studied by the use of metal(II) d-tartrates as heterogeneous chiral Lewis acid catalysts. The enantioselectivity varied widely with the combination of oxirane, nucleophile, and metal(II) d-tartrate, and Zn(II) d-tartrate gave the best enantioselectivity in the respective reactions of 1

    Enantioselective deprotonation of symmetrical epoxides was studied by using chiral lithium amide, prepared from (S)-2-(N,N-disubstituted aminomethyl)pyrrolidine and butyllithium. Chiral allylic alcohols were obtained with moderate to high enantiomeric excesses (ee’s) (41–92% ee) from several cyclic and acyclic epoxides employing lithium (S)-2-(1-pyrrolidinylmethyl)pyrrolidide in tetrahydrofuran (THF) in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU).
