  • A Practical Synthesis of α-Substituted tert-Butyl Acrylates from Meldrum’s Acid and Aldehydes
    作者:Christopher Frost、Stephen Penrose、Robert Gleave
    DOI:10.1055/s-0028-1083351
    日期:2009.2
    An expeditious synthesis of α-substituted tert-butyl acryl­ates from commercially available aldehydes and Meldrum’s acid has been established. The method benefits from a telescoped condensation-reduction sequence to afford 5-monosubstituted Meldrum’s acid derivatives followed by a Mannich-type reaction triggered by a rapid cycloreversion of the dioxinone ring on heating with tert-butyl alcohol.
    已建立了一种从商业可得的醛和Meldrum酸快速合成α-取代叔丁基丙烯酸酯的方法。该方法通过叠缩-还原序列实现,先得到5-单取代的Meldrum酸衍生物,然后在加热条件下与叔丁醇发生曼尼希型反应,触发快速环转化反应,从而形成二氧环己酮环。
