Asymmetric Transfer Hydrogenation of α-Keto Amides; Highly Enantioselective Formation of Malic Acid Diamides and α-Hydroxyamides

The asymmetric transfer hydrogenation (ATH) of α-keto-1,4-diamides using a tethered Ru/TsDPEN catalyst was achieved in high ee. Studies on derivatives identified the structural elements which lead to the highest enantioselectivities in the products. The α-keto-amide reduction products have been converted to a range of synthetically valuable derivatives.

Preparation method of 2-hydroxy acid ester

The invention relates to a preparation method of 2-hydroxy acid ester and belongs to the technical field of organic synthesis. According to the preparation method of 2-hydroxy acid ester, 2-hydroxy alkyl cyanogens is taken as a raw material to be added to a reaction solution formed by hydrogen chloride, alcohol and water, and after reaction, 2-hydroxy acid ester is obtained. According to the preparation method of 2-hydroxy acid ester, use of a large amount of nonpolar solvent is not needed, and a target product can be obtained by a one-pot method, thus lowering production cost, improving production efficiency and the purify of the target product, and having energy-saving and environment-friendly effects.

Iron-catalyzed hydrogenation for the in situ regeneration of an NAD(P)H model: Biomimetic reduction of α-Keto-/α-iminoesters

Two irons for a smoother finish: An NAD(P)H model was regenerated readily in situ by iron-catalyzed reduction with molecular hydrogen. The subsequent biomimetic reduction of α-keto-/ α-iminoesters proceeded smoothly in the presence of an iron-based Lewis acid (LA) to provide α-hydroxyesters and amino acid esters in good to excellent yields (see scheme; NAD(P) +=nicotinamide adenine dinucleotide (phosphate), TM=transition metal).

Stereoselective reduction of carbonyl compounds with actinomycete: Purification and characterization of three α-keto ester reductases from Streptomyces avermitilis

We achieved the purification of three α-keto ester reductases (Streptomyces avermitilis keto ester reductase, SAKERs-I, -II, and -III) from Streptomyces avermitilis NBRC14893 whole cells. The molecular masses of the native SAKERs-I, -II, and -III were estimated to be 72, 38, and 36 kDa, respectively, by gel filtration chromatography. The subunit molecular masses of SAKERs-I, -II, and -III were also estimated to be 32, 32, and 34 kDa, respectively, by SDS-polyacrylamide gel electrophoresis. The purified SAKERs-II and -III showed a reducing activity for α-keto esters (in particular, for ethyl pyruvate). SAKER-I showed a high reducing activity not only toward the α- and β-keto esters, but also toward α-keto acid. The N-terminal region amino acid sequences of SAKERs-I, -II, and -III were identical to that of a putative oxidoreductase, SAV2750, a putative oxidoreductase, SAV1849, and a putative oxidoreductase, SAV4117, respectively, hypothetical proteins coded on the S. avermitilis genome.

HYDROBORATION OF 1-(5-HEXENYL)PIPERIDINE AND trans-1-(3-HEXENYL)PIPERIDINE

1-(5-Hexenyl)piperidine (Ia) and trans-1-(3-hexenyl)piperidine (Ib) were hydroborated with tetrahydrofuran-borane, diborane in situ, 9-borabicyclononane and triethylamine-borane.The hydroboration products were converted to 1-piperidinylhexanols IIa-IIe by hydrolysis with hydrochloric acid and subsequent oxidation with hydrogen peroxide in an alkaline medium.In addition to the alcohols IIa-IIe, the reaction also gave 1-hexylpiperidine (Ic).In the reactions with diborane in situ and triethylamine-borane, thermal isomerisation of the hydroboration products was also studied.Hydroboration of Ia with triethylamine-borane afforded a mixture of spirocyclic amine-boranes IIIa-IIIc from which 6-(1-piperidinyl)-3-hexylboronic acid hydrochloride (IV) was obtained by hydrolysis with hydrochloric acid.Compounds IIIa-IIIc were slowly decomposed with ethanol to give esters of boronic acids Id-If.The synthesis of compounds Ia and Ib is described.
