Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2058-72-2, name is 5-Bromo-1-methylindoline-2,3-dione, A new synthetic method of this compound is introduced below., Formula: C9H6BrNO2
General procedure: General procedure forthe preparation of oxazolo[5,4-b]quinoline- fused spirooxindoles 4a-t: A reaction of isatin(1 mmol),beta-diketone (1 mmol) and5-amino-3-methylisoxazole (1 mmol) were mixed and irradiated in a closed vesselin the absence of any solvent in a Synthos 3000 microwave reactor at 700 W, 14 bar,and 110 C for 10 min. The reaction was monitored by TLC. Then, thereaction mixture was filtered hot and the resulting solid products were washed with ethanol, dried in air and recrystallized from ethanol.
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.
