The catalytic ring-closing carbonyl-olefin metathesis (RCCOM) of O-allyl salicylaldehydes to form 2H-chromenes is described. The method utilizes a [2.2.1]-bicyclic hydrazine catalyst and operates via a [3 + 2]/retro-[3 + 2] metathesis manifold. The nature of the allyl substitution pattern was found to be crucial, with sterically demanding groups such as adamantylidene or diethylidene offering optimal

A copper/(R )‐DTBM‐SEGPHOS‐catalyzed enantioselective hydroamination of 2H ‐chromenes employing hydrosilanes and hydroxylamine esters has been developed. This protocol offers a highly efficient and direct route for accessing a series of 4‐aminochromanes in 50–88 % yields with 59–99 % enantioselectivities under mild reaction conditions.
