摘要:The present invention pertains generally to the field of chemical synthesis, and more particularly to methods of chemical synthesis which include the step of preparing a substituted 10H-phenothiazine-3,7-diamine compound of Formula (1) by a step of selective alkylation by reductive amination, in which the corresponding unsubstituted diamine of Formula (4) is reacted with aldehyde/ketone, under reductive amination conditions. The present invention also relates to such methods which incorporate additional subsequent and/or preceding steps, for example, to prepare compounds of Formulae (2) and (3) from compounds of Formula (1), and to prepare compounds of Formula (4) from, for example, compounds of Formulae (5), (6), (7), (8), and (9). Compounds of Formula (1), Formula (2), and Formula (3) are useful, for example, in the treatment of diseases of protein aggregation, such as Alzheimer's disease.

摘要:Disclosed in the present invention is a method for preparing a β-trifluoromethylenamine compound on the basis of organic dye catalysis. The present invention belongs to the technical fields of the synthesis of medicines, pesticide products and material intermediates. The β-trifluoromethylenamine compound has a structure as represented by formula (I). The preparation method of the present invention comprises: under the irradiation of environment-friendly, green and economic visible light, using a catalytic amount of a commercial organic dye Na2-Eosin Y as a photocatalyst, using CF3SO2Na which is cheap, easily available, stable and simple and convenient to operate as a trifluoromethyl source, using Na2CO3 as an additive, and using tert-butyl hydroperoxide as an initiator. The reaction has mild conditions and is insensitive to air and water, and the operation is simple and convenient, the reaction efficiency is high, and the target product is easy to purify. In addition, the present invention has a a wide reaction substrate range and good functional group tolerance, and most of the target product compounds can be obtained with good to significant yields.
