Allenes are compounds with adjacent carbon—carbon double bonds. Many allenes are chiral, even though they don’t contain chirality centers. Mycomycin, for example, a naturally occurring antibiotic isolated from the bacterium Nocardia acidophilus, is chiral and has [α]_D = – 130. Explain why Mycomycin is chiral. Making a molecular model should be helpful.
