A pinch of salt: The first catalyticaddition of dialkylzincreagents 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.
