N-But-3-enyl-α- and β-amino acids can be prepared by cleaving 1,3-oxazolidin-5-ones and 1,3-oxazinan-6-ones in the presence of allylsilanes and boron trifluoride etherate at room temperature in good to excellent yields. 1,3-oxazolidin-5-ones - 1,3-oxazinan-6-ones - amino acids - allylations - Lewis acids
可以通过在室温下在烯丙基硅烷和三氟化硼醚化物存在下裂解1,3-恶唑烷五-5-酮和1,3-恶嗪南-6-酮来制备N-丁基-3-烯基-α和β-氨基酸温度高到优异的产量。 1,3-恶唑烷丁-5-酮-1,3-恶嗪南-6酮-氨基酸-烯丙基化-路易斯酸
