N‐Bromosuccinimide (NBS): A Mild and Efficient Catalyst for Tetrahydropyranylation of Alcohols and Phenols under Solvent‐Free Conditions

Abstract

Different types of alcohols and phenols are tetrahydropyranylated in the presence of NBS catalyst in good to excellent yields under mild, neutral and solvent-free conditions.

Application of N-Bromosuccinimide in Carbohydrate Chemistry

“…17,18 NBS has been widely used with various aromatic and aliphatic compounds, and its application in carbohydrate chemistry is also significant. 19,20 This review article focuses on the role of NBS in protection, deprotection, and glycosylation reactions in the field of carbohydrate chemistry.…”

Regioselective Monobromination of Phenols with KBr and ZnAl–BrO3−–Layered Double Hydroxides

“…Safer N-bromosuccinimide based analogues are developed as preferable brominating reagents [13][14][15][16][17][18][19]. However, these brominating reagents employ Br 2 in preparation and produce useless organic waste [20,21]. Oxidative bromination is another approach to brominated substrates [22][23][24][25][26].…”

Poly(N-bromo-N-ethyl-benzene-1,3-disulfonamide), N,N,N′,N′-tetrabromobenzene-1,3-disulfonamide as new efficient reagents for conversion of alcohols to THP ethers and aldehydes to oxazoline compounds

“…Several reagents have been developed as catalysts for the formation of THP ethers from alcohols and 3,4-dihydro-2H-pyran (DHP). These include p-TsOH [3], Fe(ClO 4 ) 3 [4], La(NO 3 ) 3 [8] , Al(HSO 4 ) 3 [9], LiBF 4 [10] , In(OTf) 3 [11], Nafion-H [12], heteropolyacids [13], Lithium perchlorate-diethyl ether [14] and NBS [15].…”
