Compositions and methods for sulfation of carbohydrates
In one aspect, the disclosure relates to a facile strategy to introduce electron-deficient aryl sulfate diesters to silylated hydroxyl groups of carbohydrates and amino acids, among other substrates, wherein selective hydrolysis and the removal of an electron-deficient aromatic group allows for the efficient generation of sulfated carbohydrates, peptides, and other compounds. The incorporation of electron-deficient aryl sulfate diesters in the early stage of the synthesis of glycans, peptides, and the like, disclosed herein avoids time-consuming protecting group manipulations, simplifies the purification of sulfated products, and improves the overall yield and efficiency. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

PROCESS OF PREPARING NUCLEIC ACID OLIGOMER
The present invention provides an efficient process for preparing a nucleic acid oligomer, that is, a process for preparing a nucleic acid having a phosphate triester bond effectively by oxidizing a nucleic acid precursor having a phosphite triester bond. Specifically, the present invention provides a process for preparing a nucleic acid compound having at its 5′-terminus a nucleotide represented by formula (I) by a phosphoramidite method, which comprises a step of reacting a precursor having a phosphite triester bond represented by a formula (II) (the definitions of substituents of formulae (I) and (II) are described in the Description) with an oxidation solution subjected to a heat-treatment that contains iodine, pyridine and water.
