α-Aminoamides are shown to be useful as ligands in Goldberg amidations. A number of α-aminoamides are examined and the importance of substitution on the α-aminoamides is explored. Acetamide is focused on as the nucleophilic coupling partner due to its low cost, stability and convenience as a protecting group. The initial substrate scope for these catalysts is explored and includes electronically activated
已显示α-氨基酰胺可用作戈德堡酰胺化中的配体。检查了许多α-氨基酰胺,并探讨了在α-氨基酰胺上取代的重要性。乙酰胺由于其低成本,稳定性和方便性而作为保护基团而成为亲核偶联伴侣。探索了这些催化剂的初始底物范围,包括电子活化和失活的芳基溴化物,但是o-取代的芳基溴化物是有问题的。
