Synthesis of trifluoromethylated 2H-azirines through Togni reagent-mediated trifluoromethylation followed by PhIO-mediated azirination [PDF]
Beilstein Journal of Organic Chemistry, 2018 The reaction of enamine compounds with the Togni reagent in the presence of CuI afforded β-trifluoromethylated enamine intermediates, which were converted directly to biologically interesting trifluoromethylated 2H-azirines by an iodosobenzene (PhIO ...

Synthesis of Siphonazole B Through Domino Cycloisomerization-Oxazolonium Ion Rearrangements. [PDF]
ChemistryThe study by Strand and co‐workers describes a concise synthesis of siphonazole B. Both oxazole units are formed from a simple propargylamine using a novel domino cycloisomerization‐rearrangement approach. Additional synthetic features include a direct aldol‐type reaction for assembling the tricyclic siphonazole core and an oxidative amidation reaction
