this synthesis was the formation of α-(dimethylamino)alkanenitriles as intermediates. These nitriles were successfully prepared from both aliphatic and aromatic aldehydes by reaction with dimethylamine and aqueous sodium cyanide. Treatment of the nitriles with lithium diisopropylamide (LDA) followed by reaction with various aldehydes led to the formation of α-hydroxy ketone compounds, examples of which
描述了一种新的通用合成路线,用于制备辣椒素样分子,该分子含有模拟辣椒素结构中酰胺官能团的 α-羟基酮官能团。该合成中的关键反应是形成作为中间体的 α-(二甲氨基)烷腈。通过与二甲胺和氰化钠水溶液反应,由脂肪醛和芳香醛成功地制备了这些腈。用二异丙基氨基锂 (LDA) 处理腈,然后与各种醛反应导致形成 α-羟基酮化合物,其例子包括 2-羟基-1-(4-羟基-3-甲氧基苯基)dodecan-3-一,(5R)-和(5S)-2-羟基-1-(4-羟基-3-甲氧基苯基)-5,9-二甲基dec-8-en-3-one,代表新型辣椒素样分子。(4-苄氧基-3-甲氧基苯基)乙醛的形成也由4-苄氧基-3-甲氧基苯甲醛与叶立德试剂(甲氧基甲基)三苯基溴化鏻的Wittig反应描述,然后酸水解形成标题化合物。这种醛是合成辣椒素样结构的有用前体。 (© Wiley-VCH Verlag GmbH & Co.
