Highly functionalized polyol building blocks have been synthesized by means of stereoselective chemoenzymatic C–C bond formation followed by stereoselective reduction. Catalysis by thiamine diphosphate (ThDP) dependent benzaldehyde lyase (BAL) with glyceraldehyde acetonide as acceptor substrate gave highly stereoenriched polyols such as (1S,2S,3R)-1-phenylbutane-1,2,3,4-tetrol (1), the 3,4-protected anti-1,2-diol 5, and the precursor of both compounds, 2-hydroxyketone 4.

A new versatile polythiophene building block, 3-(3,4-ethylenedioxythiophene)prop-1-yne (pyEDOT) (3), is prepared from glycidol in four steps in 28% overall yield. pyEDOT features an ethynyl group on its ethylenedioxy bridge, allowing further functionalization by alkyne chemistry. Its usefulness is demonstrated by a series of functionalized polythiophene derivatives that were obtained by pre- and post-electropolymerization transformations, provided by the synthetic ease of the Sonogashira coupling and click chemistry.

Synthesis of Cryptochiral (R,R)-2,3-Dideuterooxirane as Stereochemical Reference Compound and Chemical Correlation with D-(+)-Glyceraldehyde

Trapp, Oliver,Zawatzky, Kerstin

, p. 1082 - 1090 (2016/11/23)

Chirality plays a pivotal role in chemistry and biology, e.g., structure-specific targeting in drug development or the lock-and-key theory of enzyme interactions. Determining absolute configurations of chiral molecules is essential to understanding such mechanisms and to developing chemical processes involving chiral compounds. In particular, this becomes obvious in the understanding of chemical reaction networks in the context of the origins of life. A stereochemical reference compound that can be correlated with sugars, amino acids, etc. is of great interest. Here, we present the synthesis of enantiopure (R,R)-2,3-dideuterooxirane, of which the absolute configuration has been unambiguously determined by foil-induced Coulomb explosion imaging, and the correlation with the configuration of D-(+)-glyceraldehyde.

Oxoammonium salt oxidations of alcohols in the presence of pyridine bases

Bobbitt, James M.,Bartelson, Ashley L.,Bailey, William F.,Hamlin, Trevor A.,Kelly, Christopher B.

, p. 1055 - 1067 (2014/03/21)

Oxoammonium salt oxidations (using 4-acetylamino-2,2,6,6- tetramethylpiperidine-1-oxoammonium tetrafluoroborate) of alcohols containing a β-oxygen atom in the presence of pyridine yield dimeric esters, while in the presence of 2,6-lutidine the product is a simple aldehyde. The formation of a betaine between pyridine and an aldehyde is presented to explain this disparity in reactivity. The betaine is oxidized by the oxoammonium salt to give an N-acylpyridinium ion that serves as an acylating agent for ester formation. Steric effects deter the formation of such a betaine with 2,6-disubstituted pyridines. A series of alcohols containing a β-oxygen substituent were oxidized to aldehydes in the presence of 2,6-lutidine, and a short study of the relative reactivity of various alcohols is given. An overall mechanism for oxoammonium cation oxidations is suggested, premised on nucleophilic additions to the oxygen atom of the positively charged nitrogen-oxygen double bond. Possible mechanisms for both dimeric oxidations and simple oxidations are given.

The absolute configuration of (R,R)-2,3-dideuterooxirane, which has been independently determined using Coulomb explosion imaging, has been unambiguously chemically correlated with the stereochemical key reference (+)-glyceraldehyde. This puts the absolute configuration of D(+)-glyceraldehyde on firm experimental grounds. 100% Absolute: The absolute configuration of (R,R)-2,3-dideuterooxirane, which has been independently determined by Coulomb explosion imaging (CEI), has been unambiguously chemically correlated with the stereochemical key reference (+)-glyceraldehyde. This puts the absolute configuration of D(+)-glyceraldehyde on firm experimental grounds (see scheme).

Access to functionalized steroid side chains via modified Julia olefination

Izgu, Enver Cagri,Burns, Aaron C.,Hoye, Thomas R.

supporting information; scheme or table, p. 703 - 705 (2011/04/26)

Various functionalized steroidal side chains were conveniently accessed by a modified Julia olefination strategy using a common sulfone donor and an appropriate α-branched aldehyde acceptor. For the coupling of these hindered classes of reaction partners (and in contrast to typically observed trends), the benzothiazolyl(BT)-sulfone anion gave superior outcomes compared to the phenyltetrazolyl(PT)-sulfone anion.

Stereoselective triplet-sensitised radical reactions of furanone derivatives

Jahjah, Rabih,Gassama, Abdoulaye,Bulach, Veronique,Suzuki, Chikako,Abe, Manabu,Hoffmann, Norbert,Martinez, Agathe,Nuzillard, Jean-Marc

The stereo- and regioselectivity of triplet-sensitised radical reactions of furanone derivatives have been investigated. Furanones 7a,b were excited to the 3ππ* state by triplet energy transfer from acetone. Intramolecular hydrogen abstraction then occurred such that hydrogen was transferred from the tetrahydropyran to the β position of the furanone moiety. Radical combination of the tetrahydropyranyl and the oxoallyl radicals led to the final products 8a,b. In the intramolecular reaction, overall, a pyranyl group adds to the a position of the furanone. The effect of conformation was first investigated with compounds 9a,b carrying an additional substituent on the tether between the furanone and pyranyl moiety. Further information on the effect of conformation and the relative configuration at the pyranyl anomeric centre and the furanone moiety was obtained from the transformations of the glucose derivatives 12, 14, 17 and 18. Radical abstraction occurred at the anomeric centre and at the S′-position of the glucosyl moiety. Computational studies of the hydrogen-abstraction step were carried out with model structures. The activation barriers of this step for different stereoisomers and the abstraction at the anomeric centre and at the 6' -position of the tetrahydropyranyl moiety were calculated. The results of this investigation are in accordance with experimental observations. Furthermore, they reveal that the reactivity and regioselectivity are mainly determined in the hydrogen-abstraction step. Intramolecular hydrogen abstraction (almost simultaneous electron and proton transfer) in 3ππ * excited furanones only takes place under restricted structural conditions in a limited number of conformations that are defined by the relative configuration of the substrates. It is observed that in the biradical intermediate, back-hydrogen transfer occurs leading to the starting compound. In the case of glucose derivatives, this reaction led to epimerisation at the anomeric centre.
