Application
- Allene is extensively used in a variety of photochemical,[1][2] thermal,[1][3][4] and transition metal-mediated cycloadditions.[1]
- It can be lithiated to obtain allenyllithium which reacts with alkyl halides to afford terminal allenes.[5]
- Additional application includes the preparation of reagents such as isopropenylsilanes and isopropenylstannanes by reacting with stannyl and silyl cuprates respectively.[1][6]

Getting axed: synthesis of the title amines, bearing functionality (R(1) and R(2)), involves the enantioselective palladium-catalyzed decarboxylation of allenyl N-tosylcarbamates.

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
