Concise Asymmetric Synthesis of Kweichowenol A
Konrad, David B.,Kicin, Bilal,Trauner, Dirk
, p. 383 - 386 (2019)
An asymmetric 11-step synthesis of the polyoxygenated cyclohexene natural product kweichowenol A from the traditional Chinese medicinal herb Uvaria kweichowesis is reported. The oxygenation pattern was installed on a linear precursor by exploiting the acyclic stereocontrol of the Kiyooka aldol reaction, as well as Cram chelate-controlled Grignard reactions. Ring-closing metathesis and a selective benzoylation then gave the natural product.
Investigation of glycerol incorporation into soraphen A
Hill, Alison M.,Harris, Jonathan P.,Siskos, Alexandros P.
, p. 2361 - 2362 (1998)
Glycerol has been incorporated mid-chain into the polyketide soraphen A 1 at C-3,4 and C-11,12; the pro-(S)-hydroxymethyl group of glycerol is lost and one of the hydrogens in the pro-(R)-hydroxymethyl group is retained at C-11 which excludes hydroxymalonate as the immediate precursor to the vicinal methoxy groups at C-11,12.

Method for producing carbonyl compound

Page/Page column 16; 22, (2008/06/13)
[summary][PROBLEM TO BE SOLVED]: To provide a method for effectively producing carbonyl compound from alcohol using a ruthenium compound as an oxidation catalyst which can apply to various alcoholic compounds as starting materials, and to provide a method for effectively producing the carbonyl compound in high yield with decomposing neither the alcohol nor the produced carbonyl compound.[SOLUTION]: The method for producing carbonyl compound comprises the oxidative reaction process of alcohol using N-haloamide compound or N-haloimide compound in the presence of ruthenium compound of catalytic amount in the solvent containing organic solvent not substantially oxidized with the ruthenium compound The solvent used is solvent containing organic solvents other than the carboxylic acid; mixed solvent of pH5-14 containing organic solvent and water; or organic solvent containing base.
A practical RuCl3-catalyzed oxidation using trichlproisocyanuric acid as a stoichiometric oxidant under mild nonacidic conditions
Yamaoka, Hidenori,Moriya, Narimasa,Ikunaka, Masaya
, p. 931 - 938 (2013/09/03)
The combined use of catalytic RuCl3 (1.0 mol %) and stoichiometric trichloroisocyanuric acid (TCCA; 1.0 equiv) in the presence of n-Bu4NBr (2.0 mol %) and K2CO3 (3.0 equiv) in 1:1 MeCN/H2O at 25-45°C allows smooth oxidation of primary alcohols to carboxylic acids. Secondary alcohols can be oxidized to ketones when using the same set of the reagents in 1:1 MeCN/ H2O or 1:1 AcOEt/H2O. By proceeding under the nonacidic biphasic conditions dispensing with hazardous reagents, the oxidation reactions are applicable to structurally diverse alcohols, easy to work up, environmentally benign, and basically high-yielding.
Stereoselectivity of Intramolecular Cyclisations of Nitrones Derived from 3-Oxahept-6-enals
Gravestock, Michael B.,Knight, David W.,Lovell, Jennifer S.,Thornton, Steven R.
, p. 1661 - 1664 (2007/10/02)
Intramolecular cycloadditions of the nitrones 9 and 14 show moderate to good stereoselections in favour of the cis-fused diastereoisomers 10 or 16, respectively.
Synthesis of Methyl (+/-)-2,3-O-Isopropylideneglycerate by Electrochemical Oxidation of (+/-)-1,2-O-Isopropylideneglycerol
Schwarz, Karl-Heinz,Kleiner, Katharina,Ludwig, Ralf,Schroetter, Eberhard,Schick, Hans
, p. 503 - 504 (2007/10/02)
The anodic oxidation of (+/-)-1,2-O-isopropylideneglycerol at a silver/silver oxide electrode with a controlled potential of +0.9 V vs.SCE in 2.5 N sodium hydroxide affords sodium (+/-)-2,3-O-isopropylideneglycerate in a yield of 75percent.Treatment of this salt with dimethyl sulfate and potassium carbonate in boiling acetone leads to methyl (+/-)-2,3-O-isopropylideneglycerate in a yield of 81percent.
Synthesis and Determination of the Enantiomeric Pyrity of (R)- and (S)-2,3-Dihydroxy-3-methylbutyl p-Toluensulfonate
Schoenecker, Bruno
