Ni(II)-complexes, derived from glycine Schiff bases with chiral tridentate ligands, have been used as powerful tools for the synthesis of structurally diverse tailor-made amino acids. In this manuscript, asymmetric alkylation ... -
Asymmetric Synthesis of Tailor-Made Amino Acids Using Chiral Ni(II) Complexes of Schiff Bases. An Update of the Recent Literature
Zou, Yupiao; Han, Jianlin; Saghyan, Ashot S.; Mkrtchyan, Anna F.; Konno, Hiroyuki; Moriwaki, Hiroki; Izawa, Kunisuke; Soloshonok, Vadym Anatolievch (MDPI, 2020-06-12)
Tailor-made amino acids are indispensable structural components of modern medicinal chemistry and drug design. Consequently, stereo-controlled preparation of amino acids is the area of high research activity. Over last ... -
Asymmetric Synthesis of Tetrasubstituted α-Aminophosphonic Acid Derivatives
Maestro Burzaco, Aitor; ; López Francés, Adrián; Martínez de Marigorta Izaga, Edorta ; Palacios Gambra, Francisco Javier ; Vicario Hernando, Javier (MDPI, 2021-05-27)
Due to their structural similarity with natural α-amino acids, α-aminophosphonic acid derivatives are known biologically active molecules. In view of the relevance of tetrasubstituted carbons in nature and medicine and the ... -
Asymmetric transformations of donor-acceptor cyclopropanes under bronsted acid catalysis
(2019-10-10)Los ciclopropanos dadores-aceptores, son considerados importantes estructuras en la construcción de moleculas más complejas, debido a su tendencia termodinámica a sufrir apertura de anillo impulsada por la liberación de ... -

(2017-05-19)La memoria recoge el estudio y desarrollo de diversas reacciones organocatalíticas enantioselectivas. Explorando, en primer lugar, la utilización de alenamidas como precursores de cationes oxaalílicos en la cicloadición ... -
Asymmetries in Hungarian
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 1991)In this thesis I would like to defend the hypothesis that Hungarian is a configurational language. There has been much discussion in recent years concerning the question whether Hungarian is a configurational language or ... -
Asymptotic Comparison of the Solutions of Linear Time-Delay Systems with Point and Distributed Lags with Those of Their Limiting Equations
De la Sen Parte, Manuel (Hindawi Publishing Corporation, 2009)
This paper investigates the relations between the particular eigensolutions of a limiting functional differential equation of any order, which is the nominal (unperturbed) linear autonomous differential equations, and the ... -
Asymptotic Hyperstability and Input–Output Energy Positivity of a Single-Input Single-Output System Which Incorporates a Memoryless Non-Linear Device in the Feed-Forward Loop
De la Sen Parte, Manuel (MDPI, 2022)
This paper visualizes the role of hyperstable controllers in the closed-loop asymptotic stability of a single-input single-output system subject to any nonlinear and eventually time-varying controller within the hyperstable ... -
Asymptotic Hyperstability of a Class of Linear Systems under Impulsive Controls Subject to an Integral Popovian Constraint
De la Sen Parte, Manuel; Ibeas Hernández, Asier ; (Hindawi Publishing Corporation, 2013)
This paper is focused on the study of the important property of the asymptotic hyperstability of a class of continuous-time dynamic systems. The presence of a parallel connection of a strictly stable subsystem to an ... -
