The intramolecular 1,4-dipolar cycloaddition of an anhydro-4-hydroxy-2-oxo-1,3-thiazium hydroxide across a tethered indole π-bond has been used for the construction of the pentacyclic skeleton of epi-16,17-dihydroeburnamenine.
跨束缚的吲哚π键的脱水-4-羟基-2-氧-2-氧-1,3-噻嗪氢氧化物的分子内1,4-偶极环加成已用于构建epi -16,17-的五环骨架二氢氨苄宁。
