Synthetic Route of 1015-89-0, A common heterocyclic compound, 1015-89-0, name is Phenanthridin-6(5H)-one, molecular formula is C13H9NO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
EXAMPLE 28 STR46 To a mixture of phenanthridone 32 and PCl5 is added a molar excess of POCl3. The reaction is heated to reflux until chromatographic analysis indicates complete reaction, cooled and quenched by pouring onto ice. The aqueous layer is extracted with CHCl3. The organic layer is dried over MgSO4, filtered and evaporated to provide phenanthridine 33.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
