说明

Application

Synthesis of 4′-deoxy-4′-fluorokanamycin A and B: This study discusses the synthetic applications of Potassium hydrogenfluoride in the development of fluorinated antibiotics, highlighting its role in selective fluorination processes (Takahashi Y et al., 1992).
Reaction of 2-deoxy-6-O-[2,3-dideoxy-4,6-O-isopropylidene-2,3-(N-tosylepimino)-alpha-D-mannopyranosyl]-4,5-O-isopropylidene-1,3-di-N-tosylstreptamine with potassium hydrogenfluoride: This article explores the chemical behavior of Potassium hydrogenfluoride under specific synthetic conditions, providing insights into its role in complex organic transformations (Kobayashi Y et al., 1992).
A synthetic study of methyl 3-deoxy-3-fluoro-alpha-D-glucopyranosides from methyl 2,3-anhydro-alpha-D-allopyranosides, and synthesis of 3′-deoxy-3′-fluorokanamycin A and 3′-chloro-3′-deoxykanamycin A: This research delves into the synthesis of modified sugars using Potassium hydrogenfluoride, illustrating its utility in the creation of novel glycoside structures, which are important in drug development (Umemura E et al., 1992).

Potassium Hydrogen Fluoride.

Molander GA, et al.

e-EROS Encyclopedia of Reagents for Organic Synthesis. (2012)

Highly stereoselective synthesis of cis-alkenyl pinacolboronates and potassium cis-alkenyltrifluoroborates via a hydroboration/protodeboronation approach.

Gary A Molander et al.

The Journal of organic chemistry, 73(17), 6841-6844 (2008-08-07)

A number of alkynyl pinacolboronates bearing various functional groups were synthesized according to literature methods. These were then stereoselectively reduced to the cis-alkenyl pinacolboronates via hydroboration with dicyclohexylborane followed by chemoselective protodeboronation using acetic acid. Treatment with potassium hydrogen fluoride

Reaction of 2-deoxy-6-O-[2,3-dideoxy-4,6-O-isopropylidene-2,3- (N-tosylepimino)-alpha-D-mannopyranosyl]-4,5-O-isopropylidene-1,3-di-N- tosylstreptamine with potassium hydrogenfluoride.
