The present disclosure relates to new compounds or pharmaceutically acceptable salts or stereoisomers thereof of formula I as inhibitors of receptor tyrosine kinases (RTK), in particular extracellular mutants of ErbB-receptors. The present disclosure also relates to methods of preparation these compounds, compositions comprising these compounds, and methods of using them in the treatment of cancer in mammals (e.g. humans).

Amine oxides, 1, 5, 10, 15, 21, 23, when treated by lithium diisopropylamide undergo deprotonation.Monodeprotonation gives rise either to secondary amines and benzaldehyde resulting from the hydrolysis of an intermediate immonium (I) or to hydroxylamines via a Stevens-like rearrangement observed for the first time on an amine oxide.Double deprotonation gives an immonium ylid (Y) which, depending upon the structure of the initial tertiary amine yields either "head to head" piperazines (biradical-like behavior of (DD)) or aziridines.The immonium ylid (Y5) derived from trimethylamine oxide, whose formation and reactivity are reported for the first time, has remarkable property of undergoing cycloaddition reactions with unactivated olefins, leading to a new and efficient synthesis of various pyrrolidines.
