    2,2-二取代环氧化物的区域选择性羰基化:酮基羟醛产品的替代途径
    摘要:
    我们报告了 2,2-二取代环氧化物到 β,β-二取代 β-内酯的区域选择性羰基化。机理研究表明,环氧化物开环是周转限制步骤,这一见解有助于使用弱供体的醚溶剂开发改进的反应条件。广泛的环氧化物可以羰基化为 β-内酯,随后开环产生基于酮的醛醇加合物,为 Mukaiyama 醛醇反应提供替代方案。对映纯的环氧化物被证明经过羰基化/开环过程并保留立体化学以形成对映纯的 β-羟基酯。

    Provided are methods of carbonylating cyclic substrates to produce carbonyl ated cyclic products. The cyclic substrates may be 2, 2-di substituted epoxides and the cyclic products may be β,β-di substituted lactones. The method may be carried out by forming and pressurizing a reaction mixture of the cyclic substrate, a solvent, carbon monoxide, and a [LA+][CO(CO)4-] catalyst, where [LA+] is a Lewis acid capable of coordinating to the cyclic substrate. The method may proceed with a regioselectivity of 90:10 or greater. The resulting carbonylated cyclic products may be converted to ketone aldol products that retain the stereochemistry and enantiomeric ratio of the carbonyl ated cyclic products.
    提供了一种将环状底物羰基化以产生羰基化环状产物的方法。环状底物可以是2,2-二取代环氧化物,环状产物可以是β,β-二取代内酯。该方法可以通过形成并加压环状底物、溶剂、一氧化碳和[LA+][CO(CO)4-]催化剂的反应混合物来进行,其中[LA+]是能够与环状底物配位的路易斯酸。该方法可能以90:10或更高的区域选择性进行。所得的羰基化环状产物可以转化为保留羰基化环状产物的立体化学和对映比的酮醇产物。
