Correction to “Broadly Applicable Copper(I)-Catalyzed Alkyne Semihydrogenation and Hydrogenation of α,β-Unsaturated Amides Enabled by Bifunctional Iminopyridine Ligands”

There were two mistakes in the chemical drawings in Table 2 in the published article. Compound 12o was mistakenly depicted as the 2-substituted pyridine derivative; however, the compound prepared was the 3-pyridine derivative. Furthermore, in compound 12z the methyl ester was mistakenly shown in the 6-position of the lactam, whereas it must be correctly depicted as the regioisomeric compound with the ester in the 3-position. The complete corrected Table 2 is presented below. The correction has no influence on the data or the conclusions of the work. All data in the original Supporting Information documents are correct. All reactions were performed according to the general procedure 2 (GP2, see the Supporting Information for details) with 0.2 mmol of the substrate; isolated yields are given. Conversion was measured by GC/GC-MS and/or ¹H NMR analysis. For the (Z)-isomer, 71% of amide 12s was isolated. Gram scale reaction on a 3.4 mmol scale was also performed (75% isolated yield); CCDC: 2415987. Doubly 1,4-reduced product of lactam 11z was obtained. 19% Conversion of 11ab was observed. 29% Conversion of 11ac was observed. Double 1,4-reduced product of enamide 11ah was obtained. 23% Conversion to amide 12ah was observed along with 46% of transesterification product (not isolated). Complete 1,6 and 1,4-reduction of 11ai occurred. Hydrogenation was performed in 0.4 mmol scale. Additional 18% only 1,4-reduced product was isolated (see Supporting Information). Additional 17% only 1,4-reduced product was isolated (see Supporting Information). This article has not yet been cited by other publications.
