An efficient and diastereoselective synthetic procedure for the functionalized 1,8,9,9a-tetrahydro4H-1,4-ethanoquinolizine derivatives was successfully developed via domino reactions of 4-dimethylaminopyridine, acetylenedicarboxylates and arylidene cyanoacetates in dimethoxyethane.The similar domino reactions of 4-methoxypyridine, acetylenedicarboxylates and arylidene cyanoacetates selectively resulted in the corresponding 1,8,9,9a-tetrahydro-4H-1,4-ethanoquinolizines or buta-1,3-diene-1,2,4-tricarboxylates depending on the substrates and reaction conditions.

基于线性稳定性理论的转捩预测方法是目前工程领域被广泛采用的方法.当其应用于三维边界层时,需要确定应该沿着什么方向对扰动波的放大率进行积分.由复变函数理论中的鞍点法所给出的方向是数学上看起来最合理的结果.然而,由于不稳定波的频率,波数都可能为复数,这一结果的物理意义并不像在水波中应用鞍点法时那样明确.
