It has been generally accepted that biosynthesis of protoheme (heme) uses a common set of core metabolic intermediates that includes protoporphyrin. Herein, we show that the Actinobacteria and Firmicutes (high-GC and low-GC Gram-positive bacteria) are unable to synthesize protoporphyrin. Instead

Getting axed: synthesis of the title amines, bearing functionality (R(1) and R(2)), involves the enantioselective palladium-catalyzed decarboxylation of allenyl N-tosylcarbamates. The reaction proceeds smoothly using both the chiral ligands (S)- and (R)-DTBM-Segphos (1) to afford the allenyl amines in good
