## Abstract A new catalytic system, generated from the readily available and inexpensive β‐sulfonamide alcohol L\*, Ti(O^i^Pr)~4~, Et~2~Zn, and tertiary amine base (R~3~N), effectively catalyzes the enantioselective addition of various terminal alkynes including some quite challenging alkynes to al
