A compounds is a sort of chemical (that is) possessed of a variety of pharmaceutic and biologic activity. At precent, studying on A compounds become the prime task of syntheses of nature drugs. In this paper, an efficient method of one-pot synthesis of A by using a novel inorganic salt catalyst was mainly discoursed, and thus a series of B compounds with inoxidability were synthesised. Besides, a new idea was put forward to prepare di-B compounds with C-group. The inoxidability of final products were predicted due to the strong inoxidability of C-group. Corresponding synthetic scheme was designed to prepare the final products B from simple raw materials. Whereas, the first-phase preparations of the synthesis of C was made, and compound(s) D was prepared successfully. |
