Paragraph 0122-0124, (2021/05/28)
Chemoselective conjugation is achieved through redox reactivity by reacting an N-transfer oxidant with a thioether substrate in a redox reaction in an aqueous environment to form a conjugation product. In embodiments, Redox-Activated Chemical Tagging (ReACT) strategies for methionine-based protein functionalization. Oxaziridine (Ox) compounds serve as oxidant-mediated reagents for direct functionalization by converting methionine to the corresponding sulfimide conjugation product.

Paragraph 0125-0126, (2016/10/10)
The present invention relates to a method to synthesize an enamide compound by generating imine which does not have a substituent group bonded to the nitrogen from an organic azide compound and conducting a reaction of the same with acyl doner. By using t

The nucleophilicity of N-unsubstituted imines, which were generated from alkyl azides by a ruthenium-catalyzed reaction, was investigated in the reaction with acid anhydrides. The initial products were N-acylimines, which isomerized to the corresponding e

Described herein is a manganese-catalyzed dehydrogenative [4+2] annulation of N-H imines and alkynes, a reaction providing highly atom-economical access to diverse isoquinolines. This transformation represents the first example of manganese-catalyzed C-H activation of imines; the stoichiometric variant of the cyclomanganation was reported in 1971. The redox neutral reaction produces H2 as the major byproduct and eliminates the need for any oxidants, external ligands, or additives, thus standing out from known isoquinoline synthesis by transition-metal-catalyzed C-H activation. Mechanistic studies revealed the five-membered manganacycle and manganese hydride species as key reaction intermediates in the catalytic cycle.

Blanc, Sylvain,Bordogna, Celine A. C.,Buckley, Benjamin R.,Elsegood, Mark R. J.,Bulman Page, Philip C.
experimental part, p. 882 - 889 (2010/04/05)
A number of stable new N-H oxaziridines have been designed and prepared, and their reactivity as electrophilic sources of nitrogen investigated. 3-tert-Butyl-3-phenyloxaz-ridine is the most efficient and stable and has potential for use as a general reagent for this purpose.

Barbot, Francis,Miginiac, Leone
, p. 2601 - 2614 (2007/10/03)
Reaction of N-unsubstituted ketimines with organoaluminum reagents prepared from allylic and propargylic halides, allows to prepare, in good yields, tertiary carbinamines with three different groups (phenyl, alkyl and α-unsaturated group) on die tertiary carbon center.

, p. 635 - 638 (2007/10/02)
Ru3(CO)12 showed high catalytic activity for the deoxygenation of various ketoximes to the corresponding ketimines under carbon monoxide pressure (20 kg/cm2).For the deoxygenation of propiophenone oxime, ethyl phenyl ketimine was obtained in 100 percent yield.On the other hand, heptanal oxime which was aldoxime was dehydrated under the same conditions to the corresponding nitrile in 32 percent yield.
