  Bocdene and Mocdene Derivatives of Catechols and Catecholamines

  摘要：

  [GRAPHICS]Catechols react chemoselectively, in the presence of either alcohols, 1,2-diols, or simple phenols, with tert-butyl propynoate and with methyl propynoate to give 2-Boc-ethylidene (Bocdene) and 2-Moc-ethylidene (Mocdene) acetals, respectively, in 96-100% yields within 30 min at room temperature, provided that 150 mol % of DMAP is added. Cleavage of these acetals with pyrrolidine readily takes place (at room temperature!) in 95-100% yields, By taking advantage of the features of Bocdene acetals, novel catecholamine-related phosphate mimetics have been prepared.

• Ir-catalyzed chemoselective reduction of β-amido esters: A versatile approach to β-enamino esters

  The conversion of β-amido esters to β-enamino esters is an indispensable step for some synthetic approaches to alkaloids and related medicines. Known methods for such transformation are not only stepwise, but also proceed with low atom-efficiency. Herein, we report a direct and versatile approach that features the Ir-catalyzed chemoselective reduction of β-amido esters with 1,1,3,3-tetramethyldisiloxane

  对于某些生物碱和相关药物的合成方法，β-酰胺基酯向β-烯氨基酯的转化是必不可少的步骤。用于这种转化的已知方法不仅是逐步的，而且以低原子效率进行。本文中，我们报道了一种直接且通用的方法，其特征在于用1,1,3,3-四甲基二硅氧烷（TMDS）进行Ir催化的β-酰胺基酯的化学选择性还原。另外，在某些脂环族β-烯胺酯的13 C NMR光谱中观察到缺少某些信号。这揭示了文献中长期存在但被忽略的现象。
