RESUMEN
A synthetic protocol for the preparation of α-acyl aminocarboxamides and α-amino amidines is proposed. The selectivity toward each of these two possible products was tuned by simple modifications of the reaction conditions. A broad scope is presented, allowing access to the desired products in up to 87% (Ugi adduct) and 93% (α-amino amidine). Theoretical calculations were carried out, and the analysis led to the proposal of a new mechanistic pathway for the Ugi reaction, in which methanol acts not only as the solvent but also as a reagent. High-resolution (tandem) mass spectrometry experiments allowed the detection and characterization of the key intermediate associated with this new and alternative reaction pathway, thus supporting the theoretical proposal.

Depression is a complex condition, and its classical biological/psychosocial distinction is fading. Current guidelines are increasingly advocating psychotherapy as a treatment option. Psychodynamic psychotherapy models encompass a heterogeneous group of interventions derived from early psychoanalytic conceptualizations. Growing literature is raising awareness in the scientific community about the importance of these treatment options, as well as their favorable impact on post-treatment outcomes and relapse prevention. Considering the shifting paradigm regarding treatment of depressive disorder, the authors aim to provide a brief overview of the definition and theoretical basis of psychodynamic psychotherapy, as well as evaluate current evidence for its effectiveness.
