Abstract: The application of metabolic radiolabeling techniques to plant tetrapyrroles, i.e., chlorophyll and hemes, is complicated by the difficulty of obtaining sufficient quantities of radiolabeled aminolevulinic acid (ALA). ALA, the first committed intermediate in the tetrapyrrole… read more here.

Abstract: Quaternary benzylic centers are accessed with high atom and step economy by Ir-catalyzed alkene hydroarylation. These studies provide unique examples of the use of non-polarized 1,1-disubstituted alkenes in branch selective Murai-type hydro(hetero)arylations. Detailed mechanistic studies… read more here.
