(+/-)-2-O-(4-coumaroyl)-3-(4-hydroxyphenyl)lactic acid (1), a key intermediate in rosmarinic acid biosynthesis in higher plant cells, was established by condensation of protected 4-coumaric acid and (+/-)-3-(4-hydroxyphenyl)lactic acid followed by deprotection. A stable supply of 1 thus attained will lead to biochemical and molecular biological characterization of later steps of rosmarinic acid biosynthesis
通过缩合建立了一种简单的方法来合成(+/-)-2-O-(4-香豆酰基)-3-(4-羟苯基)乳酸(1),这是高级植物细胞中迷迭香酸生物合成的关键中间体。保护的4-香豆酸和(+/-)-3-(4-羟苯基)乳酸,然后脱保护。如此稳定供应的1将导致迷迭香酸生物合成后续步骤的生化和分子生物学表征。
