20-Epidasycarpidone (10) and its N-benzyl analogue 9 have been synthesized via a conjugate addition of 2-(1,3-dithian-2-yl)indole (6) and 3-ethyl-Δ3-piperidein-2-ones 7 and 8, respectively. The transformation of 20-epidasycarpidone to 20-epiuleine (11) has been carried out as described in the literature in order to corroborate the structural assignments.
20 Epidasycarpidone(10)和它的ñ -苄基类似物9已经通过共轭加成的合成2-(1,3-二噻烷-2-基)吲哚(6)和3-乙基- Δ 3 -piperidein -2-分别是7和8。如文献中所述,已经进行了从20-表皮果皮酮到20-表皮素的转化(11),以证实结构分配。
