Chiral Amine Synthesis – Recent Developments and Trends for Enamide Reduction, Reductive Amination, and Imine Reduction
TL;DR: The review examines the chiral amine literature from 2000-2009 concerning enantioselective and diastereoselectives methods for N-acylenamide and enamine reduction, reductive amination, and imine reduction.
Journal ArticleDOI
A Highly Enantioselective, Pd–TangPhos‐Catalyzed Hydrogenation of N‐Tosylimines
TL;DR: The search for effective hydrogenation catalysts for the reduction of N-tosylimines is explored, and the strongly electron-withdrawing character of the tosyl group reduces the inhibitory effect of the reduction product on the catalysts, which might lead to higher reactivity.
Journal ArticleDOI
A general aminocatalytic method for the synthesis of aldimines.
TL;DR: These unprecedented reactions, which presumably occur via iminium activation without requiring acidic conditions, are an interesting and competitive alternative to the classical methods for preparing aldimines.
Journal ArticleDOI
Efficient synthesis of disulfides by air oxidation of thiols under sonication
TL;DR: Alkyl, aryl and heteroaryl symmetrical disulfides can be easily obtained by heating the corresponding thiols for several hours at 80 °C with Et3N in DMF under atmospheric oxygen as mentioned in this paper.

N-tert-butanesulfinyl imines: versatile intermediates for the asymmetric synthesis of amines.
TL;DR: N-tert-Butanesulfinyl aldimines 3 and ketimines 4 are exceedingly versatile intermediates for the asymmetric synthesis of amines and provide a new family of ligands for asymmetric catalysis.

Synthesis of Enantiomerically Pure N-tert-Butanesulfinyl Imines (tert-Butanesulfinimines) by the Direct Condensation of tert-Butanesulfinamide with Aldehydes and Ketones
TL;DR: In this paper, the first general methods for the one-step preparation of N-tert-butanesulfinyl imines from aldehydes and ketones are described. But these methods are not suitable for a wide range of aldehyde classes.
