中文摘要：

-indoloquinazoline 碱 orisuaveolines A 和 B 的建议结构的第一全部的合成被报导。合成的关键步包括了 Pictet-Spengler 反应造进一步转变了成由一个一个壶冷凝作用分子的目标的六成员的酮。这合成从便宜、商业地可得到的开始的材料以一种短、方便的方式提供了存取给 orisuaveolines A 和 B 的建议结构。我们的综合产品的结构被 2D-NMR 实验证实。

英文摘要：

First total synthesis of the proposed structures of β-indoloquinazoline alkaloids orisuaveolines A and B is re- ported. The key steps of the synthesis included a Pictet-Spengler reaction to build a six-member lactam which fur- ther transformed into target molecular by a one-pot condensation. This synthesis provided an access to the proposed structures of orisuaveolines A and B in a short and convenient manner from inexpensive, commercially available starting materials. The structures of our synthesized products were confirmed by 2D-NMR experiments.
