A pinch of salt : The first catalytic addition of dialkylzinc reagents to N‐ acylpyridinium salts with good yields and excellent enantioselectivities uses a copper–( S )‐ L complex as the catalyst. The versatility of the method is illustrated in the formal synthesis of the alkaloid ( R )‐coniine. Bn=benzyl, Tf=trifluoromethanesulfonyl.
