Paragraph 0047-0048, (2017/01/23)
The invention relates to a thiadiazine compound and an asymmetric synthetic method thereof. According to the method, transition metal and chiral oxazoline ligand complexes are used as catalysts, orthanilamide and aldehyde are used as reactants, and condensation and asymmetric addition are performed, so as to obtain the chiral thiadiazine compound. The method has important application prospect in synthesizing chiral thiadiazine diuretic drugs.
