Persulfides (R−SSH) have been hypothesized as potent redox modulators and signaling compounds. Reported herein is the synthesis, characterization, and in vivo evaluation of a persulfide donor that releases N‐acetyl cysteine persulfide (NAC‐SSH) in response to the prokaryote‐specific enzyme nitroreductase. The donor, termed NDP‐NAC, decomposed in response to E. coli nitroreductase, resulting in release...
Neues gelernt: Eine Cyclisierung vom Dieckmann‐Typ ermöglichte die Synthese der Titelverbindungen mit bis zu 96 % ee (siehe Schema; Bn=Benzyl). Das Vorliegen einer β‐koordinierenden Einheit im Substrat führt zu einer Konkurrenz zwischen Cyclisierung und Eliminierung, die durch die Art des chiralen Liganden beeinflusst wird. Eine mechanistische Erklärung für diese Beobachtungen wird vorgestellt.
