Total and formal synthesis of (a) levo- and dextrorotatory enantiomer of tranylcypromine, (b) Tasimelteon, (c) TRPV1 inhibitor 24, and (d) Ticagrelor, via myoglobin-catalyzed cyclopropanation in whole cells. See SI for details on synthetic steps. DPPA = diphenylphosphoryl azide, PTSA = para-toluenesulfonic acid, T3P = propane phosphonic acid anhydride, TFA = trifluoroacetic acid.
