Efficient synthesis of the ketone body ester (R)-3-hydroxybutyryl-(R)-3-hydroxybutyrate and its (S,S) enantiomer

The ketone body ester (R)-3-hydroxybutyryl-(R)-3-hydroxybutyrate and its (S,S) enantiomer were prepared in a short, operationally simple synthetic sequence from racemic beta-butyrolactone. Enantioselective hydrolysis of beta-butyrolactone with immobilized Candida antarctica lipase-B (CAL-B) results in (R)-beta-butyrolactone and (S)-beta-hydroxybutyric acid, which are easily converted to (R) or (S)-ethyl-3-hydroxybutyrate and reduced to (R) or (S)-1,3 butanediol. Either enantiomer of ethyl-3-hydroxybutyrate and 1,3 butanediol are then coupled, again using CAL-B, to produce the ketone body ester product. This is an efficient, scalable, atom-economic, chromatography-free, and low cost synthetic method to produce the ketone body esters.

A new case of induced helical chirality in a bichromophoric system: Absolute configuration of transparent and flexible diols from the analysis of the electronic circular dichroism spectra of the corresponding di(1-naphthyl)ketals

(Chemical Equation Presented) Di(1-naphthy)ketals of 1,n-diols show couplet effects allied to the 1B naphthalene transition in their CD spectra. This means that they assume a conformation with a prevailing sense of twist of the naphthalene rings, imposed by the absolute configuration (AC) of the starting diols and by the nature of the R1 groups. A positive couplet for aliphatic diols is a probe of (R,R), AC while the opposite sign is found for (R,R) aromatic diols.

Enantioselective Propargylation of Polyols and Desymmetrization of meso 1,2-Diols by Copper/Borinic Acid Dual Catalysis

A copper/borinic acid dual catalytic reaction enabled the enantioselective propargylation of aliphatic polyols. Readily available reagents and catalysts were used in this transformation, which displayed good to excellent chemo- and stereoselectivity for a broad array of substrates. The method was also applicable to the desymmetrization of meso 1,2-diols to furnish products with three stereogenic centers and a terminal alkyne group in one operation.
