Embodiment 1
[0037] Compound 1 of the present invention (see attached for the structural formula figure 1 ), when R 1 = -OCH 3 , R 2 =CH 3 The compound a is extracted from natural plants.
Embodiment 2
[0039] Compound formula 2 is synthesized as follows:
[0040]
[0041] The first step: in a 100 mL round bottom flask, add 1 g (1 equivalent) of reactant (1) and 4.10 g (1 equivalent) of reactant (2). Under the protection of argon, add 50 mL of anhydrous DMF solvent. After all the reactants were dissolved, 272 mg (1.1 equivalent) of sodium hydride was added at 0°C. After the reaction was stirred at 0°C for 2 hours, the temperature was gradually raised to room temperature; then the stirring was continued overnight. After the reaction is completed, most of the DMF is removed under high vacuum, and then the reaction concentrate is extracted with dichloromethane. The organic phases were combined, washed with saturated sodium bicarbonate and saturated brine, and concentrated with a rotary evaporator. Finally, the reaction product (3) is purified through a silica gel separation column. Final product: 2.65 g; Yield: 90%. Mass spectrum (HRMS, ESI): 288.1161 (M+1). Elemental analysi...
Embodiment 3
[0045] Compound formula 3 is synthesized as follows:
[0046]
[0047] The first step: In a 100 mL round-bottom flask, add 1 g (1 equivalent) of reactant (1) and 4.72 g (1 equivalent) of reactant (5). Under argon protection, add 50 mL of anhydrous DMF solvent. After all the reactants were dissolved, 272 mg (1.1 equivalent) of sodium hydride was added at 0°C. After the reaction was stirred at 0°C for 2 hours, the temperature was gradually raised to room temperature; then the stirring was continued overnight. After the reaction is completed, most of the DMF is removed under high vacuum, and then the reaction concentrate is extracted with dichloromethane. The organic phases were combined, washed with saturated sodium bicarbonate and saturated brine, and concentrated with a rotary evaporator. Finally, the reaction product (6) is purified by a silica gel separation column. Final product: 2.77 g; Yield: 85%. Mass spectrum (HRMS, ESI): 318.1259 (M+1). Elemental analysis: C, 64.35;...
