Stereoselective Synthesis of Morpholines via Copper-Promoted Oxyamination of Alkenes
, 2016 A new copper(II) 2-ethylhexanoate-promoted addition of an alcohol and an amine across an alkene (oxyamination) is reported. The alcohol addition is intramolecular, while coupling with the amine occurs intermolecularly.

A One-Pot Reaction toward the Diastereoselective Synthesis of Substituted Morpholines
, 2018 The diastereoselective synthesis of various substituted morpholines has been achieved from vinyloxiranes and amino-alcohols under sequential Pd(0)-catalyzed Tsuji–Trost/Fe(III)-catalyzed heterocyclization.

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Synthesis of Enantiopure 3-Substituted Morpholines
, 2016 Enantiopure 3-substituted morpholines were assembled through ring-opening of a N-2-benzothiazolesulfonyl (Bts) activated aziridine with organocuprates followed by a ring annulation reaction with a vinylsulfonium salt under microwave conditions ...

From classroom to clinic: Evaluating the educational utility of two Thiel embalming methods
Anatomical Sciences Education, EarlyView.Abstract Over three decades since its introduction, the Thiel embalming method remains a widely used and praised technique in anatomical education and clinical training. This study compared for the first time the Thiel original protocol (TO) and a Modified version (TM) across user groups—undergraduate medical students, student demonstrators in anatomy,

A General, Enantioselective Synthesis of Protected Morpholines and Piperazines
, 2016 A short, high yielding protocol has been developed for the enantioselective and general synthesis of C2-functionalized, benzyl protected morpholines and orthogonally N,N′-protected piperazines from a common ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate
Chemistry – A European Journal, EarlyView.A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Synthesis of nitrogen-containing heterocycles : tetrahydropyrazines and morpholines
, 2018 Les tétrahydropyrazines et les morpholines sont des hétérocycles à six chaînons comportant deux hétéroatomes en position 1,4. Les objectifs de cette thèse ont été la mise au point de nouvelles méthodes pour leur synthèse.
