| titleOfInvention | Stereoselective method for the preparation of nucleoside analogues |
| abstract | The present invention relates to a method for producing an excellent cis nucleosides of the formula (A) or nucleoside homolog derivatives thereof,n n n n n n n n (Wherein R 1 is a pyridine base or a pharmaceutically acceptable derivative thereof and Q is oxygen, carbon, sulfur)n n n The process of coupling the pyridine base and the compound of formula (B) in an appropriate coupling solvent in the presence of a catalytic amount of an element or a combination of elements of group IB or IIB of the Periodic Table of Elements, in the presence of tertiary amines and Lewis acids ) To obtain an intermediate mixture, which is then deprotected to produce the compound of formula (A). |
