We distribute TCI NEWS every four weeks,
to our valued customers using research chemicals and
chromatography products. We hope that you find this
helpful for your research.
Product] Labeled N-Glycans based on Chemical
chemical synthesis of oligosaccharide using various sugar
building blocks provides various structure-defined N-glycans
such as human type glycans (G0, G2 and SG), uniform
isomer (each G1 and G1’ ) and heterogenic antigen
(including αGal or NeuGc). We produce high grade 2-AB
labeled N-glycans based on chemical synthetic
technology. Please take advantage of our fluorescent-labeled
product portfolio as standard glycans for MS, CE and HPLC
TCIMAIL contains technical papers
contributed by leading professors and scientists. We also
introduce our new reagents in the fields of synthetic
organic chemistry, materials chemistry, bioscience and
analytical science. Examples of application and use are
explained in an easy way, using various schemes and
Recyclable Iodobenzene Supported on Magnetite for
Oxidation of 4-Alkoxyphenols
A magnetite supported iodobenzene (1)
substrate use for the oxidation of hydroquinones has
recently been developed by Yakura et al. In the
presence of co-oxidants, 1 acts as a hypervalent
iodine species to catalyze the oxidation of
4-alkoxyphenol (2). Furthermore, due to its
ferromagnetic nature, 1 can be recycled and
recovered through the use of a general purpose magnet.
Yakura et al . reported that catalytic activity
was not significantly lost after 5 recycles of 1,
and quinone (3) was still obtained in good yield.
Ruthenium Catalyst for the meta-Selective
(1), a ruthenium complex used to catalyze C-H bond
functionalizations has been recently reported by
Ackermann et al. In the presence of catalytic
amounts of 1, substituted benzene derivatives are
regioselectively alkylated at the meta-position by
treatment with secondary alkyl halides in good yield.1)
Furthermore, when o -alkylbenzoic acid derivatives
are treated with alkenes and the catalyst 1, meta-alkenylated
arenes are provided via decarboxylative C-H bond
activation.2) In addition,1 is
effective at C(sp3)-H activation of
benzylamine derivatives.3)1 can be
used as a catalyst for various types of aryl
functionalization through C-H bond activation.
