Continuous multistep synthesis of 2-(azidomethyl)oxazoles

Beilstein Journal of Organic Chemistry, 2018
An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl ...

Intramolecular Azide to Alkene Cycloadditions for the Construction of Pyrrolobenzodiazepines and Azetidino-Benzodiazepines [PDF]

, 2014
The coupling of proline- and azetidinone-substituted alkenes to 2-azidobenzoic and 2-azidobenzenesulfonic acid gives precursors that undergo intramolecular azide to alkene 1,3-dipolar cycloadditions to give imine-, triazoline- or aziridine-containing ...

Azetidinylideneketenimines as a Multimodal Synthetic Platform: Coordination Chemistry and Cycloaddition‐Triggered Transformations

Angewandte Chemie, EarlyView.
Cross‐coupling/homologation sequence between a stable three‐membered‐ring carbene and isocyanides enables facile and rapid access to novel methyleneketenimines and the first bis(methyleneketenimine). Reactivity studies gave rise to the first methyleneketenimine‐transition metal complexes, unique multimodal reactivity ranging from CO2, isocyanate ...

Expeditious diastereoselective synthesis of elaborated ketones via remote Csp3–H functionalization

Nature Communications, 2017
C-H activation is a powerful method to form functionalised molecules, but is particularly challenging for unactivated sp3sites. Here the authors report a directing-group-free radical cascade process for converting vinyl azides and carboxylic acids to ...

Sulfonylative and azidosulfonylative cyclizations by visible-light-photosensitization of sulfonyl azides in THF [PDF]

, 2017
The generation of sulfonyl radicals from sulfonyl azides using visible light and a photoactive iridium complex in THF is described. This process was used to promote sulfonylative and azidosulfonylative cyclizations of enynes to give several classes of ...

Water-mediated synthesis of disubstituted 5-aminopyrimidines from vinyl azides under microwave irradiation

Green Chemistry Letters and Reviews, 2018
An efficient and ecofriendly method for the synthesis of disubstituted 5-aminopyrimidines from vinyl azides and urea or thiourea was developed. This reaction proceeds under microwave irradiation conditions in the presence of water as a solvent.
