摘要:
The invention relates to a method for the enantioselective preparation of substituted sulphoxide derivatives. The method comprises carrying out an enantioselective oxidation of a sulphide of general formula (I): A-CH2—S—B (I), where A=a variously-substituted pyridyl nucleus and B=a heterocyclic group with a benzimidazole or imidazopyrdyl nucleus, by means of an oxidising agent in the presence of a catalyst based on tungsten or vanadium and a chiral ligand, followed, where necessary, by salt formation with a base to give the sulphoxide: A-CH2—SO—B (Ia). The above is of application to the enantioselective preparation of compounds such as the enantiomers of tenatoprazole and other comparable sulphoxides.
摘要:
The present invention concerns enantioselective preparation of sulphoxide derivatives or their salts. The method consist in performing an enantioselective oxidation of a sulphur of general formula (I) A-CH2—SB, wherein: A is a diversely substituted pyridinyl ring and B is a heterocyclic radical comprising an imidazo-pyridinyl ring, using an oxidizing agent in the presence of a titanium (IV)-based catalyst and a chiral ligand consisting of a cyclic beta or gamma-amino-alcohol, in an organic solvent, followed, if required, by salt formation with a base. The invention is useful for preparing sulphoxides useful in therapeutics.
