Abstract A concise and efficient method for the large-scale total synthesis of oxyphyllacinol (1) has been achieved in six steps with an overall yield of 46%. Simultaneously, yakuchione-A (11) was obtained in a satisfactory yield (52%) during the process. By employing a Weinreb amide (6) as the key masonry block, yakuchione-B (13) was also constructed in a great overall yield (56%) and high purity
摘要 一种简洁高效的大规模全合成羟茶醇( 1 )方法分六步完成,总收率为46%。同时,在该过程中以令人满意的产率(52%)获得了yakuchione-A(11 )。通过使用 Weinreb 酰胺 ( 6 ) 作为关键砌块,yakuchione-B ( 13 ) 也以很高的总产率 (56%) 和高纯度构建。为了克服实用规模、高纯度和重现性方面的挑战,所处理的合成路线利用了现有材料、常规反应和方便的纯化方法,无需使用柱色谱。
