Reconciliation of Time Perspectives as a Criterion for Therapy Completion
No full textGiancarlo Trombini, the main author of this article, has demonstrated in a series of empirical studies based on treatment examples from psychoanalytic psychotherapy that the development of relational dynamics in therapy can be assessed in an objectively verifiable way using a phenomenological criterion based on the narrative content of each session. This criterion is the comparison between the manifest dream and the subsequent associations (MDAC; Trombini, 2010, 2014, 2015).
This is a contribution to the reflexive pole of analytic psychotherapy, which is, after all, characterized by a constant oscillation between the pole of reflection and the pole of a “dreaming reception.” The present contribution continues this research with the treatment of the concluding phase of therapy, which is related to certain turning points in the processes of change in therapy (Di Chiara, 2003)

The Organocatalytic α-Fluorination of Chiral γ-Nitroaldehydes: the Challenge of Facing the Construction of a Quaternary Fluorinated Stereocenter
No full textChiral γ-nitroaldehydes 1 are easily accessible by the organocatalytic Michael addition of aldehydes to nitroalkenes. In this paper, we report the organocatalytic fluorination of 1 with N-fluorobenzenesulfonimide (NFSI) leading to the highly stereoselective construction of a challenging quaternary fluorinated stereocenter at the α position of α,α-dialkyl aldehydes. The reaction takes place via a chiral trisubstituted enamine, so far rather unexplored in the field of organocatalysis. Fluorinated products 3 are direct precursors of chiral monofluorinated 3,4-polysubstituted pyrrolidines. Mechanistic details are discussed with the aid of computational results
Organocatalytic Conjugate Addition of Nitroalkanes to 3-Ylidene Oxindoles: A Stereocontrolled Diversity Oriented Route to Oxindole Derivatives
No full textAn efficient and highly enantioselective Michael addition of nitroalkanes to 3-ylidene oxindoles is described, mediated by thiourea-based bifunctional organocatalysts. The stereochemistry at C-alpha and C-beta centers is perfectly controlled, and the intermediate C-3 enolate is trapped with a second Michael acceptor. The developed one-pot three-component consecutive reactions generate up to four contiguous stereocenters, including the C-3 all-carbon quaternary center, in a perfectly defined configuration. The conversion of the beta-nitro oxindole into the corresponding beta-amino derivative discloses synthetically useful transformations, exploitable to generate pharmaceutically attractive molecular targets
