Ti-Mediated Synthesis of Spirocyclic NH-Azetidines from Oxime Ethers.
Angewandte Chemie, 2019 The Ti(IV)-mediated synthesis of spirocyclic NH-azetidines from oxime ethers with an alkyl Grignard reagent or terminal olefin ligand exchange coupling partner is described. Through a proposed Kulinkovich-type mechanism, a titanacyclopropane intermediate

Synthesis of alkaloids by a diastereoselective allylation of chiral N-sulfinyl imines [PDF]
, 2016 The indium-promoted allylation of chiral N-sulfinyl imines represents a useful and versatile procedure to prepare chiral protected homoallyl amines in a diastereoselective manner. Desulfinylation under acidic conditions liberates easily the corresponding
