Enantioselective Synthesis of Homo-N-Nucleosides Containing a 1,4-Dioxane Sugar Analog
Yu, Qiang; Carlsen, Per Henning (Journal article; Peer reviewed, 2008)A dioxane homo-sugar analog, (2S,5S)-and (2R,5S)-5-[(4S)-2,2-dimethyl-1,3- dioxolan-4-yl]-2-iodomethyl-1,4-dioxane was prepared from (2R,3R)-dimethyl tartrate, and further elaborated into the corresponding homo-N-nucleoside ... -
HPLC Analysis of Aliphatic Sulfonate Surfactants using Ion-Pair Detection
Zahrobsky, M; Camporese, D; Rist, Øystein; Carlsen, Per Henning (Journal article; Peer reviewed, 2005)A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, ... -
Regioselectivity in the thermal rearrangement of unsymmetrical 4-methyl-4H-1,2,4-triazoles to 1-methyl-1H-1,2,4-triazoles
Gautun, Odd Reidar; Carlsen, Per Henning (Journal article; Peer reviewed, 2001)The rearrangement of 4-methyl-3,5-diaryl-4H-1,2,4-triazoles to the corresponding 1-methyl-3,5-diaryl-1H-1,2,4-triazoles showed regioselectivity comparable to that observed for the alkylation of 3,5-diaryl-1H-1,2,4-triazoles. ... -
Synthesis of a Novel Benzoyl Adenosine Analog Containing a 1, 4-Dioxane Sugar Analog and the Synthesis of a Corresponding Uracil Adenine Dinucleotide
Yu, Qiang; Carlsen, Per Henning (Journal article; Peer reviewed, 2011)Adenosine analogs in which the sugar unit was replaced by a 1,4-dioxane sugar equivalent, were prepared by coupling the 1,4-dioxane sugar analog as its anomeric acetates, with N6-benzoyl protected adenine. The 1,4-dioxane ... -
Synthesis of Hydroxy Sulfonate Surfactants
Rist, Øystein; Carlsen, Per Henning (Journal article; Peer reviewed, 2005)The selective synthesis of sulfonate surfactants with side chains containing ether- and hydroxy groups was carried out using cyclic sulfates as epoxide analogues. The main chain was elaborated from 1,2-dodecane sulfate ... -
Synthesis of Novel Homo-N-Nucleoside Analogs Composed of a Homo-1,4-Dioxane Sugar Analog and Substituted 1,3,5-Triazine Base Equivalents
Yu, Qiang; Schwidom, Dirk; Exner, Alexander; Carlsen, Per Henning (Journal article; Peer reviewed, 2008)Enantioselective syntheses from dimethyl tartrate of 1,3,5-triazine homo-Nnucleoside analogs, containing a 1,4-dioxane moiety replacing the sugar unit in natural nucleosides, were accomplished. The triazine heterocycle ... -
Synthesis of polynucleotide analogs containing a polyvinyl alcohol backbone
Yu, Qiang; Carlsen, Per Henning (Journal article; Peer reviewed, 2008)Water soluble homo-base polynucleotide analogues were synthesized in which polyvinyl alcohol and partially phosphonated polyvinyl alcohol constituted the backbones, onto which were grafted uracil or adenine via 1,3-dioxane ... -
Synthesis, Characterization and Drug Loading of Multiresponsive p[NIPAm-co-PEGMA] (core)/p[NIPAm-co-AAc] (Shell) Nanogels with Monodisperse Size Distributions
Raju, Rajesh; Bandyopadhyay, Sulalit; Sharma, Anuvansh; Gonzalez, Susana Villa; Carlsen, Per Henning; Gautun, Odd Reidar; Glomm, Wilhelm (Journal article; Peer reviewed, 2018)We report the synthesis and properties of temperature- and pH-responsive p([NIPAm-co-PEGMA] (core)/[NIPAm-co-AAc] (shell)) nanogels with narrow size distributions, tunable sizes and increased drug loading efficiencies.
