A facile and efficient synthesis of pyrrolesfrom readily available amino acids is described. The key step in the method is an aza-Wacker oxidative cyclization catalyzed by palladium(II)/Cu(OTf)2. A series of pyrroles were obtained by this method under mild conditions.
light‐induced C−H amination of heteroarenes can be accomplished with preformed iodine(III) reagents as the combined oxidant and nitrogen source. The reaction requires the use of a small amount of molecular iodine, which under photochemical activation generates in situ an iodine(I) reagent as the initiator of the radical amination reaction. A total of 32 examples exemplify the broad scope of the transformation

vinyl sulfone reagent was shown to efficiently label two cysteine-tagged proteins, ubiquitin and C2Am, under mild conditions (1–5 equiv. of reagent in NaPi pH 7.0, room temperature, 30 min). The resulting thioether-linked conjugates were stable and retained the native activity of the proteins. Finally, the dienophile present in the azabicyclic moiety on a functionalised C2Am protein could be fluorescently
Asymmetric Synthesis of Tropanes by Rhodium-Catalyzed [4 + 3] Cycloaddition

Rhodium-catalyzed [4 + 3] cycloadditionbetween methyl 2-(siloxy)vinyldiazoacetate and pyrroles results in the enantioselective synthesis of highly functionalized 8-azabicyclo[3.2.1]octa-2,6-dienes (tropanes). The reaction proceeds via a rhodium−carbenoid intermediate and involves a tandem cyclopropanation/Cope rearrangement mechanism. The optimum chiral dirhodium catalyst for this transformation is
