Trimethyl β-(methoxy)orthopropionate, a compound which is thermally stable at 190 °C for prolonged times, may be utilized as a synthon for the preparation of methyl α-substituted acrylates via Claisen ortho ester rearrangement with allylic alcohols followed by β-elimination of methanol with base.
β-(甲氧基)原丙酸三甲酯是一种在190°C长时间热稳定的化合物,可以用作合成子,通过克莱森原酸酯与烯丙醇的重排,然后进行β消除,来制备甲基α-取代的丙烯酸酯的甲醇与碱。
