X-Ray analyses of 1-hydroxyyohimbine derivatives definitely show the deviation of the N(1)—O bond from the indole molecular plane. This fact supports our working hypothesis “bishomoallylic conjugation”. The deviation is responsible for the rearrangement reaction in 1-hydroxyindole chemistry. Effective synthetic method for novel 7 and 7 -heteroarylyohimbine, and 4a and 4a -heteroaryl-1,2,3,4-tetrahydro-carboline
1-羟基育亨宾衍生物的 X 射线分析明确显示了 N(1)-O 键与吲哚分子平面的偏差。这一事实支持我们的工作假设“双烯丙基共轭”。这种偏差是 1-羟基吲哚化学中重排反应的原因。报道了新型7和7-杂芳基育亨宾以及4a和4a-杂芳基-1,2,3,4-四氢咔啉衍生物的有效合成方法。引言 吲哚是一种具有 sp2 杂化氮的平面杂芳族分子。2 在我们的 1-羟基吲哚假说 3 中,我们预计一旦将羟基引入到其氮上,尤其是在这种情况下
