Viruses . 2022 May; 14(5). PMID: 35632703
The coronavirus disease 2019 (COVID-19) pandemic is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a recently emerged human coronavirus. COVID-19 vaccines have proven to be successful in...

Sharland J, Wei B, Hardee D, Hodges T, Gong W, Voight E, et al.
Chem Sci . 2021 Sep; 12(33):11181-11190. PMID: 34522315
This study describes general methods for the enantioselective syntheses of pharmaceutically relevant 1-aryl-2-heteroaryl- and 1,2-diheteroarylcyclopropane-1-carboxylates through dirhodium tetracarboxylate-catalysed asymmetric cyclopropanation of vinyl heterocycles with aryl- or heteroaryldiazoacetates. The reactions are...

Angew Chem Int Ed Engl . 2015 Nov; 55(2):539-44. PMID: 26612607
Quinones are important organic oxidants in a variety of synthetic and biological contexts, and they are susceptible to activation towards electron transfer through hydrogen bonding. Whereas this effect of hydrogen...

J Am Chem Soc . 2010 Mar; 132(14):5002-3. PMID: 20297823
The first example of aromatic cation-activated nucleophilic acyl substitution has been achieved. The conversion of carboxylic acids to their corresponding acid chlorides occurs rapidly in the presence of 3,3-dichlorocyclopropenes via...

Hardee D, Lambert T
J Am Chem Soc . 2009 Jun; 131(22):7536-7. PMID: 19489639
A new method for cyclopropanation involving intramolecular methylene transfer from an epoxide to an olefin has been developed. This La(OTf)(3)-catalyzed process proceeds with good efficiency and with high stereoselectivity. A...
