An efficient route based upon solvolytic fragmentation of a cyclopentadiene-dichloroketene adduct 4c has been investigated for the synthesis of trimethoxyphenylpropyltropolone 2b, a synthetic intermediate of colchicine 1a. Attempted synthesis of the corresponding unsaturated tropolones 8a and 10 is also discussed.
我们研究了一条基于
环戊二烯-二
氯乙烯加合物 4c 溶解破碎的高效路线,用于合成三
甲氧基苯基丙基伯罗酮 2b(
秋水仙碱 1a 的合成中间体)。此外,还讨论了相应的不饱和
三苯乙烯酮 8a 和 10 的尝试合成。
