A synthetic route for obtaining 1-butoxy-1,3,3-triethoxy[1,3-2H2]propane a stable diacetal of the malondialdehyde, is described. The synthesis involves the condensation of deuterated butylvinyl ether with deuterated triethyl orthoformate in the presence of montmorillonite clay K-10. The deuteration of butyl vinyl ether was accomplished via the intermediary formation of a stannane derivative which was quantitatively metallated by n-butyllithium and then treated with 2H2O. From the diacetal the 1,3-dideuterated malondialdehyde was obtained by a short treatment with acid ion exchange resin.
本文介绍了一种获得 1-丁氧基-1,3,3-三乙氧基[1,3-2H2]丙烷的合成路线,这是一种稳定的丙二醛二缩醛。合成过程包括在蒙脱石粘土 K-10 的存在下,氘化乙烯基丁醚与氘化原甲酸三乙酯的缩合。丁基乙烯基醚的氘化是通过中间产物锡烷衍生物的形成完成的,该衍生物被正丁基锂定量金属化,然后用 2H2O 处理。通过酸性离子交换树脂的短暂处理,从二缩醛中得到了 1,3-二氚代丙二醛。
