Embodiment 1
[0085] Synthesis of Example 1 Intermediate 3-substituted phenyl-5-hydroxymethyl-isoxazole (II-A) or intermediate 3-substituted phenyl-5-aminomethyl-isoxazole (II-B) :
[0086] Using substituted benzaldehyde as raw material, it is prepared by synthesis of oxime, 1,3-dipolar cycloaddition reaction, methylsulfonyl esterification reaction, azidation, and reduction reaction (R and n are as above), see the following process for details :
[0087]
[0088] The specific synthetic process of intermediate 3-substituted phenyl-5-hydroxymethyl-isoxazole (II-A) or intermediate 3-substituted phenyl-5-aminomethyl-isoxazole (II-B) is detailed See the preparation process in the applicant's previous application with publication numbers CN103360382A, CN103664991A and CN103601762A, the full text of which is incorporated herein as a reference.
Embodiment 2
[0089] Synthesis of ferrocene derivatives (Z is O) shown in embodiment 2 formula (IA)
[0090] The reaction of 1,1'-ferrocenedicarboxylic acid and 3-phenyl-5-hydroxymethyl-isoxazole is used as an example to illustrate:
[0091] Synthesis of ferrocene dicarboxylate derivatives (YJP-1):
[0092]
[0093] Add 0.274g (1mmol) 1,1'-ferrocenedicarboxylic acid and 0.412g (2mmol) DCC into a 50mL round-bottomed flask, add 10mL dry THF, and stir in an ice bath for 30min to dissolve 0.35g (2mmol) 5-Hydroxymethyl-3-phenyl-isoxazole and 0.244g (2mmol) DMAP in 10mL THF solution were slowly added dropwise to the reaction system, stirred in an ice bath for 30min, and then naturally rose to room temperature for reaction. After the TLC detection reaction was completed, the reaction solution was concentrated in vacuo, and the residue was directly separated by column (V (石油醚) :V (乙酸乙酯) =5:1~2:1) to obtain the target compound ferrocene dicarboxylate derivative (YJP-1).
[0094] The remaining...
Embodiment 3
[0095] Synthesis of ferrocene derivatives (Z is NH) shown in embodiment 3 formula (IA)
[0096] The reaction of 1,1'-ferrocenedicarboxylic acid and 3-phenyl-5-aminomethyl-isoxazole is used as an example to illustrate:
[0097] Synthesis of ferrocenedicarboxamide derivatives (YJP-20):
[0098]
[0099] Add 0.274g (1mmol) 1,1'-ferrocenedicarboxylic acid, 0.412g (2mmol) DCC and 0.270g (2mmol) HOBt into a 50mL round bottom flask, add 10mL of dry THF, and stir in an ice bath for 30min. A solution of 0.348g (2mmol) 5-aminomethyl-3-phenyl-isoxazole and 0.244g (2mmol) DMAP in 10mL THF was slowly added dropwise to the reaction system, stirred in an ice bath for 30min, and then naturally rose to room temperature for reaction. After the TLC detection reaction was completed, the reaction solution was concentrated in vacuo, and the residue was directly separated by column (V (石油醚) :V (乙酸乙酯) =5:1~2:1) to obtain the target compound ferrocenedicarboxamide derivative (YJP-20).
