Abstract |
The preparation of (S)-3-methylamino-3-[(R)-pyrrolidin-3-yl]propanenitrile (1), a key fragment of fluoroquinolone antibiotic PF-00951966 and others was achieved by N-methylative aziridine ring opening, addition of methyl group at the ring nitrogen, and ring-opening via a cyanide nucleophile in a single operation starting from bicyclic (R)-2-[(R)-pyrrolidine-3-yl]aziridine. The starting compound was elaborated from stereoselective conjugate addition of nitromethane to (R)-aziridine-2-yl acrylate followed by selective reduction without breaking the aziridine ring.
