Enantioselective synthesis of alpha-methylene-beta-hydroxy carboxylic acid derivatives via a diastereoselective aldol/beta-elimination sequence: application to the C(15)-C(21) fragment of tedanolide C.

ABSTRACT: An enantioselective synthesis of alpha-methylene-beta-hydroxy carboxylic acid derivatives via a highly diastereoselective, one-pot syn-aldol and beta-elimination sequence utilizing the chiral beta-(phenylselenyl)propionyl imide 15 is described. This new method, which constitutes an alternative to the Baylis-Hillman reaction, has been applied to the synthesis of the C(15)-C(21) fragment of tedanolide C.

Enantioselective synthesis of the C1-C11 fragment of tedanolide C.

Project description:A convergent synthesis of the protected C(1)-C(11) fragment 6 of the targeted enantiomer of tedanolide C is described. The key step of the synthesis is the Felkin-Ahn addition of vinyl iodide 7 to aldehyde 8 that proceeds in 80% yield with 4:1 diastereoselectivity.

An Enantio- and Diastereoselective Chemoenzymatic Synthesis of ?-Fluoro ?-Hydroxy Carboxylic Esters.

Project description:The trans-o-hydroxybenzylidene pyruvate aldolase-catalysed reactions between fluoropyruvate and many (hetero)aromatic aldehydes yield aldol adducts without subsequent dehydration. Treatment of the reaction products with hydrogen peroxide yields the corresponding syn-configured ?-fluoro ?-hydroxy carboxylic acids which have >98?% ee. The overall chemoenzymatic approach, in which fluoropyruvate serves as a fluoroacetate equivalent, may be exploited in the synthesis of polar building blocks and fragments with potential value in drug discovery.

A convenient enantioselective decarboxylative aldol reaction to access chiral ?-hydroxy esters using ?-keto acids.

Project description:We show a convenient decarboxylative aldol process using a scandium catalyst and a PYBOX ligand to generate a series of highly functionalized chiral ?-hydroxy esters. The protocol tolerates a broad range of ?-keto acids with inactivated aromatic and aliphatic ?-keto esters. The possible mechanism is rationalized.

Enantio- and diastereoselective synthesis of syn-?-hydroxy-?-vinyl carboxylic esters via reductive aldol reactions of ethyl allenecarboxylate with 10-TMS-9-Borabicyclo[3.3.2]decane and DFT analysis of the hydroboration pathway.

Project description:An enantio- and diastereoselective synthesis of syn-?-hydroxy-?-vinyl carboxylate esters 3 via the reductive aldol reaction of ethyl allenecarboxylate (2) with 10-trimethylsilyl-9-borabicyclo[3.3.2]decane (1R) has been developed. Density functional theory calculations suggest that the allene hydroboration involves the 1,4-reduction of 2 with the 1R, leading directly to dienolborinate Z-(O)-8a.

Double diastereoselective, nucleophile-catalyzed aldol lactonizations (NCAL) leading to beta-lactone fused carbocycles and extensions to beta-lactone fused tetrahydrofurans.

Project description:A double diastereoselective variant of the nucleophile-catalyzed aldol lactonization (NCAL) process is described. This strategy delivers beta-lactone-fused carbocycles with good to excellent diastereoselectivities using cinchona alkaloid catalysts with enantioenriched aldehyde acids, which gave low diastereoselectivity based on substrate control alone. beta-Lactone-fused tetrahydrofurans are also prepared for the first time via the NCAL process; however, diastereoselectivity was only modestly improved when applying double diastereodifferentiation to these systems.

Stereochemically versatile synthesis of the C1-C12 fragment of tedanolide C.

Project description:A flexible synthesis of the C1-C12 fragment of Tedanolide C has been accomplished in eight steps from 2-methyl-2,4-pentadienal. Asymmetric hydroformylation of a 1,3-diene allows for the late-stage generation of either C10 epimer with complete catalyst control. Diastereoselective addition of an isobutyryl ?-ketoester dianion to an ?,?-disubstituted chiral aldehyde sets the C5 stereochemistry while installing the geminal dimethyl unit. Differential protection of a syn-1,3-diol is performed as a highly efficient single-pot operation.

Synthesis of β-hydroxy-α-haloesters through super silyl ester directed syn-selective aldol reaction.

Project description:Super silyl haloesters including chloro- and bromoacetate were synthesized and utilized for aldol reactions to give syn-β-hydroxy-α-haloacetates in good yields with high diastereoselectivities. β-Hydroxy-α-fluoroacetate was obtained by lithiation of super silyl bromofluoroacetate. Sequential Darzens reactions provided cis-glycidic esters in moderate yields.

Direct catalytic enantio- and diastereoselective ketone aldol reactions of isocyanoacetates.

Project description:A catalytic asymmetric aldol addition/cyclization reaction of unactivated ketones with isocyanoacetate pronucleophiles has been developed. A quinine-derived aminophosphine precatalyst and silver oxide were found to be an effective binary catalyst system and promoted the reaction to afford chiral oxazolines possessing a fully substituted stereocenter with good diastereoselectivities and excellent enantioselectivities.

Activation of Hydroxy-carboxylic Acid Receptor 1 effect on cardiomyocytes

Project description:Our aim is to explore the effect of Hydroxy-carboxylic Acid Receptor 1 on cardiomyocytes. Neonatal rat cardiomyocytes (NRCMs) were isolated and cultured. Subsequently, NRCMs were treated with the agonist of Hydroxy-carboxylic Acid Receptor 1 (HCAR1), 3Cl-HBA at 40 μM for 48 h(HBA1,HBA2 and HBA3) or DMSO as control(C1,C3 and C3). RNA was extracted using the KAPA RiboErase RNA-Seq kit (Roche, Basel, Switzerland), and was analysed using the Agilent Bioanalyzer 2100 system (Agilent Technologies, CA, USA) for quality control. The libraries were sequenced on an Illumina HiSeq X Ten platform. DESeq2 was used to analyse RNA-seq data. Neonatal rat cardiomyocytes (NRCMs) were isolated and cultured.
