ω-Aminodithioester derivatives were obtained from thionolactams by reaction with an alkyl triflate followed by thiolysis with hydrogen sulfide. The presence of an electron-withdrawing group was required on the N1 position (p-nitrophenyl or benzoyl) to favor the ring opening of γ-, δ- and ε-thionolactams. In the case of β-thionolactam, activation was provided by a CF2 motif in C3 position. Georg Thieme Verlag Stuttgart.
