  Asymmetric hydrogenation of the C–C double bond of 1- and 1,2-methylated maleimides with cultured suspension cells of Marchantia polymorpha

  摘要：

  Suspension cultured cells of Marchantia polymorpha have the potential to hydrogenate the C-C double bonds of 2-methyl- and 2,3-dimethylmaleimide derivatives to give enantiomerically pure (2R)-2-methyl- and (2R, 3R)-2, 3-dimethylsuccinimide derivatives, respectively.

  reagents, stoichiometric carbon monoxide and amines is described for the first time, which can be adapted to late‐stage carbon‐isotope labeling. This work expands the scope of the highly established palladium‐promoted version of the reaction, by allowing carbon‐sp3 fragments to take part in the three‐component reaction. Finally, the results obtained show a remarkable effect of the pincer ligand for

• Asymmetric bioreduction of activated carbon–carbon double bonds using Shewanella yellow enzyme (SYE-4) as novel enoate reductase

  Shewanella yellow enzyme (SYE-4), a novel recombinant enoate reductase, was screened against a variety of different substrates bearing an activated double bond, such as unsaturated cyclic ketones, diesters, and substituted imides. Dimethyl- and ethyl esters of 2-methylmaleic acid were selectively reduced to (R)-configured succinic acid derivatives and various N-substituted maleimides furnished the desired (R)-products in up to >99% enantiomeric excess. Naturally occurring (+)-carvone was selectively reduced to (-)-cis-dihydrocarvone and (-)-carvone was converted to the diastereomeric product, respectively. Overall SYE-4 proved to be a useful biocatalyst for the selective reduction of activated C=C double bonds and complements the pool of synthetic valuable enoate reductases. (C) 2012 Elsevier Ltd.

• Selective ammonolysis and aminolysis of dimethyl succinate. Synthesis of optically active N-alkylsuccinimides
  作者：Susana Puertas、Francisca Rebolledo、Vicente Gotor

  日期：1995.1

  Candida antarctica lipase catalyzes the selective monoammonolysis and aminolysis of dimethyl succinate with ammonia and aliphatic amines, respectively, in dioxane as solvent. This enzyme shows a high enatioselectivity when racemic amines are used. Optically active amidoesters are also obtained in the reaction of dimethyl succinate with racemic alpha-methylalkylamines in hexane as solvent. In this medium, the enzyme catalyzes the formation of N-alkylsuccinimides or optically active N-alkyl-alpha-methylsuccinimides from dimethyl succinate or alpha-methylsuccinate and amines.
• Efficient asymmetric hydrogenation of the C–C double bond of 2-methyl- and 2,3-dimethyl-N-phenylalkylmaleimides by Aspergillus fumigatus
  作者：Maximiliano Sortino、Susana Alicia Zacchino

  DOI：10.1016/j.tetasy.2010.02.017

  日期：2010.3

  Eight N-phenylalkylmaleimides (four 2-methyl-N-phenylalkylmaleimides and four 2,3-dimethyl-N-phenylalkylmaleimides with an alkyl chain (CH(2))(n) (n = 1-4) between the imide N and the benzene ring) were subjected to biotransformation using the fungal strain Aspergillus fumigatus ATCC 26934. All compounds were reduced enantioselectively to their respective succinimides: (R)-2-methyl-N-phenylalkylsuccinimides and (2R,3R)-2,3-dimethyl-N-phenylalkylsuccinimides, with satisfactory conversion rates and high stereoisomeric excesses. NMR analysis using the chiral shift reagent Eu(hfc)(3) showed that enantiomeric excesses were >99%. (C) 2010 Elsevier Ltd. All rights reserved.
