derived from proline undergoes a smooth ene cyclization with aldehydes to produce the 7-oxa-1-azaspiro[4.5]decane scaffolds in good yields. Whereas the condensation of γ-hydroxyalkene with 2-hydroxybenzaldehyde affords the corresponding tetrahydro-2H-spiro[pyrano[3,2-c]chromene-3,2′-pyrrolidine derivatives in excellent yields. This is the first report on the ene cyclization of aldehydes with γ-hydroxyalkene

C−H Bond Activation Relay (CHAR) of Proline Ester Derivatives Promoted by In Situ Triarylamine Radical Cation: Selective Synthesis of 4‐Bromopyrrole Derivatives
A C−H activation relay (CHAR) of proline esters was realized by the in situ generated tris(4-bromophenyl)amine radical cation, selectively constructing the skeleton of 4-bromopyrrole under mild reaction conditions.

An enantioselective propargylation of aldehydes using an allenylzinc reagent generated in situ via a zinc-iodine exchange reaction is described. The enantioselectivity is controlled by addition of a catalytic amount of readily accessible and highly tunable amino alcohol ligand L13. A wide range of aldehydes can be propargylated to afford valuable and versatile homopropargyl alcohols in good to excellent yields with high levels of enantiopurity.
