- A DNA-Encoded Chemical Library Incorporating Elements of Natural Macrocycles
-
Here we show a seven-step chemical synthesis of a DNA-encoded macrocycle library (DEML) on DNA. Inspired by polyketide and mixed peptide-polyketide natural products, the library was designed to incorporate rich backbone diversity. Achieving this diversity, however, comes at the cost of the custom synthesis of bifunctional building block libraries. This study outlines the importance of careful retrosynthetic design in DNA-encoded libraries, while revealing areas where new DNA synthetic methods are needed.

- A novel catalytic asymmetric route towards skipped dienes with a methyl-substituted central stereogenic carbon
-
A highly efficient method for the enantioselective synthesis of 1,4-dienes (skipped dienes) with a methyl-substituted central stereogenic carbon using copper-catalysed asymmetric allylic alkylation of diene bromides was developed. Excellent regio- and enantioselectivity (up to 97 : 3 SN2′/ SN2 ratio and 99% ee) were achieved with broad substrate scope. The Royal Society of Chemistry 2013.

- Extending the stetter reaction with 1,6-acceptors
-
Pace Stetter: A new N-heterocyclic carbene (NHC)-catalysed transformation is described-the intramolecular vinylogous Stetter reaction. This transformation can be effected with both thiazolium and triazolium-based catalysts, using aromatic and aliphatic aldehydes, employing α,β,γ,δ- unsaturated esters, ketones, phosphonates and N-acylpyrroles, and can be conducted enantioselectively (see scheme).

- Ruthenium-catalyzed regio- and enantioselective allylic substitution with water: Direct synthesis of chiral allylic alcohols
-
Less is more: A new route to access chiral allylic alcohols through the regio- and enantioselective substitution of monosubstituted allylic chlorides with water has been developed. The reaction is catalyzed effectively by planar-chiral cyclopentadienyl ruthenium complexes (see scheme). Copyright

- Syntheses of structurally diverse amino acids, including δ-hydroxylysine, using the acyl nitroso Diels-Alder reaction
-
By virtue of its ability to introduce amino and hydroxy functionalities in a 1,4-relationship with fully controlled relative stereochemistry, the acyl nitroso Diels-Alder (ANDA) reaction is ideally suited to the synthesis of structurally diverse, includin

- Synthesis of two bioactive natural products: FR252921 and pseudotrienk acid B
-
Concise and highly convergent syntheses of the immunosuppressive agent FR252921 and the related antimicrobial natural product pseudotrienic acid B were achieved from a common intermediate by using optically active titanium complexes to control the configuration of the stereogenic centers, a highly stereoand regioselective cross-metathesis to generate the triene moieties, and a Stille cross-coupling to install the dienic units.
