Hollerbach, Michael R.,Hayes, Jacob C.,Barker, Timothy J.
supporting information, p. 1646 - 1648 (2019/02/07)
Benzylation reactions of N-tosylimines and N-tert-butanesulfinyl imines using benzylboronic acid pinacol ester are reported. s-Butyllithium was used to activate the boronic ester, rendering it nucleophilic. The reaction was compatible with electronically
A new manganese-mediated, cobalt-catalyzed threecomponent synthesis of (diarylmethyl)sulfonamides
Pignon, Antoine,Le Gall, Erwan,Martens, Thierry
, p. 425 - 431 (2014/03/21)
The synthesis of (diarylmethyl)sulfonamides and related compounds by a new manganese-mediated, cobalt-catalyzed three-component reaction between sulfonamides, carbonyl compounds and organic bromides is described. This organometallic Mannich-like process allows the formation of the coupling products within minutes at room temperature. A possible mechanism, emphasizing the crucial role of manganese is proposed.
Tetrabenzylhafnium as a new organometallic reagent for imine addition resulting in α-branched amines
Mei, Haibo,Ji, Xiaoyun,Han, Jianlin,Pan, Yi
supporting information; experimental part, p. 5783 - 5786 (2011/11/06)
Tetrabenzylhafnium has been explored as a new organometallic reagent for the imine addition reaction. This reagent tolerates a wide scope of imines, affording α-branched amines in excellent yields without the use of any additive or catalyst. This new reag
Reductive opening of aziridines with polymethylhydrosiloxane
Chandrasekhar,Ahmed, Moinuddin
, p. 9325 - 9327 (2007/10/03)
Regio and chemoselective reductive opening of aziridines is achieved using catalytic palladium on charcoal and polymethylhydrosiloxane (PMHS) as a soluble hydrogen source.
Conversion of Chiral Oxiranes into Chiral Aziridines with Retention of Configuration by Way of Chiral Episulfonium Ions and Reactions of the Aziridines with Grignard Reagents
Toshimitsu, Akio,Abe, Hideyuki,Hirosawa, Chitaru,Tamao, Kohei
, p. 3465 - 3472 (2007/10/02)
Chiral oxiranes are converted into chiral aziridines with overall retention of configuration by means of sulfur chemistry.The key step of this procedure is the transformation of the organosulfur intermediates, i.e., the replacement of a hydroxy group boun
