The synthesis of trifluoromethylthiolated ketenimines is herein described. They are easily synthesized from the corresponding α‐trifluoromethylthiolated oximes upon activation with triflic anhydride and a base. The presumed nitrilium ion resulting from the Beckmann rearrangement is deprotonated to lead to the key intermediate, whose stability brought by the fluorinated substituent was unforeseeable

Compounds or their pharmaceutically acceptable salts can inhibit the G12D mutant of Kirsten rat sarcoma (KRAS) protein and are expected to have utility as therapeutic agents, for example, for treating cancer. The disclosure also provides pharmaceutical compositions which comprise compounds disclosed herein or pharmaceutically acceptable salts thereof. The disclosure also relates to methods for use of the compounds or their pharmaceutically acceptable salts in the therapy and prophylaxis of cancer and for preparing pharmaceuticals for this purpose.
Trifluoromethanesulfenamide reagents constitute a family of very efficient reagents to trifluoromethylthiolate various molecules. Optimized syntheses have been developed to easily obtain, in a reproducible manner, large quantities of these reagents, with good overall yields. Up to 84 g have already been obtained, at a reasonable cost.
