A tetrazolium red-based colorimetric assay has been devised to screen for transketolase activity with a range of aldehyde acceptors. The colorimetric TK assay is able to detect >8% bioconversion using non-α-hydroxylated aldehydes as acceptor substrates an

A metal-free oxyacetoxylation method of primary, secondary and tertiary propargylic carboxylates with retention of chirality was presented. The reaction proceeds through the intramolecular nucleophilic attack of the neighboring carbonyl group on an alkynyliodonium intermediate. The process is general with broad substrate scope and is amenable for application to a variety of propargyl carboxylates including those obtained from natural products. Insight into the mechanistic pathway by isotopic labelling (using H2O18 and D2O) and controlled experiments confirmed. (Figure presented.).

An operationally simple protocol is reported to generate an α-hydroxyacyl anion by the decarboxylation of dihydroxyfumaric acid. To date, the "missing" utilization of the hydroxyacyl anion in highly chemo- and stereoselective cascade reactions enables sho
α,α′-Dihydroxyketone formation using aromatic and heteroaromatic aldehydes with evolved transketolase enzymes

Transketolase mutants have been identified that accept aromatic acceptors with good stereoselectivities, in particular benzaldehyde for which the wild type enzyme showed no activity.
