General Description

(2R)-hydroxypropanal, also known as L-glyceraldehyde, is a chemical compound with the molecular formula C3H6O2. It is a sugar-derived aldehyde that is chiral, meaning it has a non-superimposable mirror image. (2R)-hydroxypropanal is an important intermediate in several biochemical pathways, including the metabolism of glucose and the production of energy in cells. It is also a key precursor in the synthesis of amino acids and nucleotides, which are essential building blocks for proteins and DNA. Additionally, (2R)-hydroxypropanal has applications in various industrial processes, including as a starting material for the production of pharmaceuticals and fine chemicals.

Stereostructure of komodoquinone A, a neuritogenic anthracycline, from marine Streptomyces sp. KS3

The absolute stereostructure of komodoquinone A (1), a neuritogenic anthracycline, which was isolated from a cultured marine Streptomyces sp. KS3, has been determined on the basis of chemical derivatization. Komodoquinone A (1) induces neuronal cell differentiation in the neuroblastoma cell line, Neuro 2A and arrests the cell cycle at the G1 phase. The effect of a solid-state medium on the production of 1 and its aglycone, komodoquinone B (2), was examined.

Biocatalytic Construction of Quaternary Centers by Aldol Addition of 3,3-Disubstituted 2-Oxoacid Derivatives to Aldehydes

The congested nature of quaternary carbons hinders their preparation, most notably when stereocontrol is required. Here we report a biocatalytic method for the creation of quaternary carbon centers with broad substrate scope, leading to different compound classes bearing this structural feature. The key step comprises the aldol addition of 3,3-disubstituted 2-oxoacids to aldehydes catalyzed by metal dependent 3-methyl-2-oxobutanoate hydroxymethyltransferase from E. coli (KPHMT) and variants thereof. The 3,3,3-trisubstituted 2-oxoacids thus produced were converted into 2-oxolactones and 3-hydroxy acids and directly to ulosonic acid derivatives, all bearing gem-dialkyl, gem-cycloalkyl, and spirocyclic quaternary centers. In addition, some of these reactions use a single enantiomer from racemic nucleophiles to afford stereopure quaternary carbons. The notable substrate tolerance and stereocontrol of these enzymes are indicative of their potential for the synthesis of structurally intricate molecules.

The first practical approach to optically pure cyclopropanes derived from trans γ-hydroxy enones

The optically pure cyclopropanes derived from trans γ-hydroxy enones were discussed. The trans γ-hydroxy enones were found to be prepared from reaction of stabilized ketoylides on optically pure α hydroxy aldehydes. The analysis showed that the use of light and a triplet sensitizer lead to a dramatic increase in reaction rate and isolated yield.
