Selective Deprotection of N -Tosyl Alkoxyamines Using Bistrifluoromethane Sulfonimide: Formation of Oxime Ethers
Azizi, Mohamed Salah,Cossy, Janine
, p. 2417 - 2421 (2018)
The detosylation of N -tosyl alkoxyamines was realized by treatment with benzaldehyde and bistrifluoromethane sulfonimide as the catalyst to afford the corresponding oxime ethers. The reaction is chemoselective as N -tosyl amines are not deprotected. A me

Toward the total synthesis of acremoxanthone A, a model study has revealed a convergent approach to construct the ABCDE ring system. The key steps include: (1) an effective construction of the bicyclo[3.2.2]nonane skeleton, (2) protocol for generating the bridgehead anion and trapping, and (3) 1,3-dipolar cycloaddition of a nitrile oxide to the internal alkene.
Reactions of N-Acyl-O-arylhydroxylamines: Part IV - Preparation of Some N-Arylsulphonyl-O-arylhydroxylamines
Singha, A. S.,Misra, B. N.
, p. 361 - 363 (2007/10/02)
A number of N-arylsulphonyl-O-alkylhydroxylamines (III) have been prepared by condensing appropriate alkoxyamines with arylsulphonyl chlorides in the presence of a base.The alkoxyamines have been obtained from the corresponding alkoxyamine hydrochlorides or hydrobromides (II) which in turn have been prepared by the hydrolysis of appropriate N-benzoyl-O-alkylhydroxylamines (I) with ethanolic hydrogen chloride or hydrogen bromide.The structure assignments of III are based on elemental analyses, chemical reaction and spectral (IR, PMR) data.
