The dipeptidic dihydroxyethylene isostere (27, 3R , 4R , 5S )-5-tert -butyloxy-carbonylamino-3,4-dihydroxy-2-isopropyl-3,4-O,O -isoprop-ylidene-6-cyclohexyl-hexanoic acid, 15 , is a representative building block of an important class

Is Permethylation Strategy Always Applicable to Protein N-Glycosylation Study: A Case Study on the O-Acetylation of Sialic Acid in Fish Serum Glycans

. However, permethylation, the most common mass spectrometric analytical means, leads to the loss of O-linked acetyl groups in sialic acids. In this chapter, we demonstrated that O-acetylation of sialic acid in Atlantic salmon serum N-glycan can be well investigated

Biotinylation of a Propargylated Cyclic (3′‐5′) Diguanylic Acid and of Its Mono‐6‐Thioated Analog Under “Click” Conditions

in a yield of 40% after P (III) oxidation and purification. Complete removal of the nucleobases, phosphates, and 2??O ?tert ?butyldimethylsilyl protecting groups leads to the desired propargylated c?di?GMP diester. Cycloaddition of a biotinylated azide
