The total synthesis of (+)-uniflorine A has allowed for the structural reassignment and the configurational assignment of the alkaloid (-)-uniflorine A from a 1,2,6,7,8-pentahydroxyindolizidine structure to (-)-(1 R,2 R,3 R,6 R,7 S,7a R)-1,2,6,7-tetrahydroxy-3-hydroxymethylpyrrolizidine (6- epi-casuarine).
(+)-uniflorine A的总合成可以使生物碱(-)-uniflorine A从1,2,6,7,8-五羟基吲哚并咪唑结构向(-)-(1)进行结构重新分配和构型分配R,2 R,3 R,6 R,7 S,7a R)-1,2,6,7-四羟基-3-羟甲基吡咯烷核苷(6-表-酪氨酸)。
