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.

Azetidin-2-iminium salts, which are readily available from tertiary amides, can be easily converted into the corresponding thiones or imines.
Synthesis of beta-lactams from azetidine carboxylic acid esters
-
, (2008/06/13)
Azetidine carboxylic acid esters are converted into enol silyl ethers which, as enamino ketene acetals, undergo ready oxidative cleavage of the ethylenically unsaturated double bond, e.g. by dye-sensitized photo-oxygenation, to form beta-lactams. The beta
