The methyl ester of 2-fluoro-3-methoxyacrylic acid and the corresponding acyl chloride can be used for the efficacious synthesis of fluorine bearing pyrazolones, pyrimidines, coumarines and benzothiopyranones. Depending on the C3F component and the conditions employed, the same cyclization partner (e.g., 2-aminothiophenol) may lead to two or even three different products.
2-氟-3-甲氧基丙烯酸的甲酯和相应的酰氯可用于有效合成含氟吡唑啉酮,嘧啶,香豆素和苯并硫代吡喃酮。取决于C 3 F组分和所用条件,相同的环化伙伴(例如2-氨基硫酚)可能会产生两种或什至三种不同的产物。
