The invention relates to a process to prepare a compound of the following formula (I): (I), in which P represents a protective group of a hydroxyl function which is a —COR.sup.1 group with R.sup.1 representing an aryl or a (C.sub.1C.sub.6)alkyl, R represents a hydrogen atom or a protective group of a terminal alkyne, from mannose, comprising the following steps: (a) protecting the 5 hydroxyl groups of the mannose by a protective group P; (b) coupling the protected mannose obtained at step (a) with a compound of the following formula (II). The present invention also relates to a compound of formula (IIIa). ##STR00001##

The present invention provides a crystalline and an amorphous form of a Molnupiravir and methods of making the crystalline form and amorphous form of Molnupiravir.

The invention relates to a process for the preparation of an allulose syrup containing allulose at a product concentration of more than 70 wt.-%, relative to the total weight of the allulose syrup, the process comprising the steps of (a) providing an aqueous solution containing allulose at an educt concentration of at most 70 wt.-%, relative to the total weight of the solution; and (b) evaporating water at a temperature of the solution of less than 60° C. and under reduced pressure thereby increasing the concentration of allulose in the aqueous solution starting from the educt concentration until the product concentration is reached.

Allulose crystals are efficiently produced from an allulose syrup using seed crystals.

Methods for cleaving oligonucleotides from a solid support are described as are methods for synthesizing an oligonucleotide on a solid support and subsequently cleaving the oligonucleotide from the solid support. In the methods, the 3′ nucleoside of the oligonucleotide attached to the solid support is a LNA nucleoside. The method entail treating the bound oligonucleotide with a concentrated ammonium hydroxide solution for about 30 minutes to about 6 hours.
