A general and efficient method for the synthesis of pronucleotide (ProTide) 5'-phosphoramidate monoesters is reported. This method consists of a highly stereoselective 5'-phosphorylation mediated by dimethylaluminum chloride to afford the desired target ProTides in excellent yields without employing 3'-protection strategies. The application of this methodology to the synthesis of a number of pharmaceutically relevant compounds currently marketed or under investigation in clinical research is demonstrated.

Paragraph 0043; 0045; 0046; 0047, (2016/05/19)
The present invention relates to phosphoric acid/phosphonic acid derivatives shown by formula (I), wherein, R1 or R2 represents the following structures: (Q1), or (Q2), or (Q3). Q1 represents ester derivatives of L-amino acid, wherein R3 is alkyl with 1-6 carbon atoms or cycloalkyl, R4 is H or alkyl with 1-6 carbon atoms; Q2 represents hydroxyl substituted benzodioxane derivatives; Q3 represents hydroxyl substituted benzodioxolane derivatives; R1 or R2 is the same or different, but at least one of them is Q2 or Q3; D represents residues of pharmacologically active molecules containing a phosphate/phosphonate group, i.e. formula (II) represents pharmacologically active molecules containing a phosphate/phosphonate group; and when R1 and R2 are different, the configuration of the P atom connected to R1 and R2 is of R or S type.
