  • Asymmetric, Catalytic, and Direct Self-Aldol Reaction of Acetaldehyde Catalyzed by Diarylprolinol
    作者:Yujiro Hayashi、Sampak Samanta、Takahiko Itoh、Hayato Ishikawa
    DOI:10.1021/ol802438u
    日期:2008.12.18
    An asymmetric, catalytic, and direct self-aldol reaction of acetaldehyde was catalyzed by diarylprolinol in NMP, affording the trimer acetal, which was generated by the reaction of the self-aldol product with another acetaldehyde molecule in a moderate yield with good enantioselectivity. Acetal is the synthetic equivalent of the self-aldol product, which can be converted into other synthetically useful
    二芳基脯氨醇在NMP中催化乙醛的不对称,催化和直接的自身醛醇缩合反应,得到三聚体乙缩醛,它是通过自身醛醇产物与另一个乙醛分子以中等收率和良好的对映选择性反应而生成的。乙缩醛是自醛醇缩合产物的合成等同物,可以在一个罐中将其转化为其他合成有用的化合物,而不会损害对映选择性。
  • A New Set of Isoreticular, Homochiral Metal–Organic Frameworks with ucp Topology
    作者:Michael Sartor、Timo Stein、Frank Hoffmann、Michael Fröba
    DOI:10.1021/acs.chemmater.5b03723
    日期:2016.1.26
    motif and a novel set of homochiral linkers has been synthesized. Starting from amino acids available from the chiral pool a synthesis procedure was established that allows a straightforward, multigram scale synthesis of homochiral linkers in 4–5 steps. These linkers carry substituents that have been proven useful in stereoselective organic chemistry, such as the Evans auxiliary or chiral amino alcohols
    基于铜桨轮基序和一组新的同手性连接基,已经合成了一个新的等网状金属-有机骨架系列,称为UHM-25(UHM:汉堡材料大学)。从手性库中可用的氨基酸开始,建立了合成程序,该程序允许在4-5个步骤中直接,数克规模的同手性连接体合成。这些接头带有已被证明可用于立体选择性有机化学的取代基,例如伊文思助剂或手性氨基醇。所得的MOF仅在氨基酸原料提供的手性部分上有所不同。UHM-25的结构由Cu 2的立方八面体笼组成通过连接子的间苯二甲酸酯部分连接的桨轮图案。这些笼通过连接子的弯曲骨架连接在一起,从而形成原始的立方排列,从而产生了稀有的下层(3,4)-c双齿净ucp。UHM-25系列的MOF的表面积高达S BET = 1900 m 2 / g。具有优良转化率的合成后修饰反应证实了手性基团的可及性。此外,带有丙醇功能的UHM-25-Pro被用于乙醛的自定向对映选择性醇醛加成中,证明了UHM-25系列在多相,立体选择性催化方面的潜力。

    An acetal protected 4-amino-2-pentanone was synthesised by two different routes in 10 and seven steps, respectively, the key step being a microbiological reduction. Both enantiomers of the amine were obtained enantiomerically pure. (C) 1999 Elsevier Science Ltd. All rights reserved.
  • METHOD FOR THE ENZYMATIC PRODUCTION OF CHIRAL ALCOHOLS
    申请人:Pfaller Rupert
    公开号:US20070212766A1
    公开(公告)日:2007-09-13
    A method of producing a chiral secondary alcohol in which a biotransformation composition containing a ketone of the formula (I), R 1 and R 2 being different and each being an organic radical, an oxidoreductase and a co-substrate is reacted to form a chiral secondary alcohol with the adsorbent being associated with the oxidoreductase. The adsorbent associated with the oxidorecutase is separated off from the biotransformation composition after completion of the reaction.
