(R)-(–)-2-Acetyl-5,8-dimethoxy-1,2,3,4-tetrahydro-2-naphthol 6, a key intermediate for the synthesis of anticancer anthracyclines, has been synthesized enantioselectively in 39% overall yield (8 steps) starting from highly diastereoselective reaction of 1-trimethylsilylbuta-2,3-diene with the chiral acetal 7.
(R)-(-)-2-乙酰基-5,8-二甲氧基-1,2,3,4-四氢-2-萘酚 6 是合成抗癌蒽环类化合物的一个关键中间体,该化合物是由 1-三甲基硅基丁-2,3-二烯与手性缩醛 7 的高非对映选择性反应开始合成的,总产率为 39%(8 个步骤)。
