## Abstract Two highly efficient protocols for enantioselective synthesis of 2,4‐dimethyl‐1‐penten‐1,5‐ylidene derivatives involve the combined use of the Zr‐catalyzed methylalumination of alkynes (ZMA) and the Zr‐catalyzed asymmetric carboalumination of alkenes (ZACA). The ZMA/ZACA protocol has be
