the “syn” diastereoisomers an unexpected rearrangement occurred during the deprotection step. This was attributed to a transient hexacoordinate fluorosilicon complex allowing the formation of a 1,2-dioxetane. Its decomposition gave aldehyde 12 and 4-hydroxybutan-2-one; these compounds were also identified when acidic conditions were used in the deprotection step. The anti amino compounds obtained were
在寻找新的抗疟内过氧化物的过程中,我们开发了一种直接途径来制备属于 G 因子系列的新氨基化合物。在合成过程中,观察到两个系列非对映异构体之间的反应性存在显着差异。最终的氨基内过氧化物以 58% 到 70% 的产率获得,这取决于起始胺,在“反”系列中,但对于“syn”非对映异构体,在去保护步骤期间发生了意外的重排。这归因于允许形成 1,2-二氧杂环丁烷的瞬态六配位氟硅络合物。其分解得到醛12和4-羟基丁-2-酮;当在去保护步骤中使用酸性条件时,这些化合物也被鉴定出来。测试所得抗氨基化合物,
