The first total synthesis of (±)-lycoricidine and confirmation of its full structure were established. In the synthesis of a key compound, 4H-r, 1H-trans, 2H-cis, 10bH-trans, -1-(2'-tetrahydropyranyloxy)-2-hydroxy-8, 9-methylenedioxy-1, 2, 4a, 10b-tetrahydro-6 (5H)-phenanthridone (14), Sharpless's procedure for preparation of allyl alcohols from epoxides using selenophenolate and hydrogene peroxide was applied.
首次完成了 (±)-lycoricidine 的全合成,并确认了其完整结构。在合成关键化合物 4H-r,1H-反式,2H-顺式,10bH-反式,-1-(2'-四氢吡喃氧基)-2-羟基-8,9-亚甲二氧基-1,2,4a,10b-四氢-6 (5H)-菲啶酮(14)时,采用了 Sharpless 使用硒苯酚和过氧化氢从环氧化物制备烯丙基醇的程序。
