A novel synthesis of hexahydroapoerysopine dimethyl ether (11), by photolytic intramolecular arylation of the 6′-iodo- and 7-bromo-derivatives of 1,2,3,3a,4,5-hexahydro-N-(3,4-dimethoxyphenethyl)indol-6-one (6) and (8) to 2,3-dihydroapoerysopin-1(3aH)-one (9), followed by reduction with LiAlH4 to cis-2,3,3a,12c-tetrahydroapoerysopine (10) and then hydrogenation, is reported.
hexahydroapoerysopine的一种新颖的合成二甲醚(11),由所述6'-碘-和-1,2,3的7-溴衍生物,4,5-六氢的光解分子内的芳基化ñ - (3,4-将二甲氧基苯乙基)吲哚-6(1)和(8)合成2,3-二氢载脂蛋白-1(3a H)-1 (9),然后用LiAlH 4还原为顺式-2,3,3a,12c-四氢载脂蛋白(10)然后氢化。
