α-Keto hydrazones behave as suitable precursors of nucleophilic β-amino aza-dienamine intermediates. Using a multifunctional tert-Leucine derived amino-thiourea as the catalyst, this reactivity was exploited to perform asymmetric 1,4-addition to ni

In this study, we report a highly stereoselective and versatile synthesis of spiro pyrazolones, promising motifs that are being employed as pharmacophores. The new synthetic strategy merges organocatalysis and metal catalysis to create a synergistic
