  碳酸诱导的位阻酮的Mukaiyama Aldol型反应

  摘要：

  1,1,3,3-四（三氟甲磺酰基）丙烷（Tf 2 CHCH 2 CHTf 2）是对位阻酮的Mukaiyama aldol型反应最有效的布朗斯台德酸预催化剂之一。通过使用0.5〜2.0摩尔％的Tf 2 CHCH 2 CHTf 2，α-取代的环己酮与2-甲硅烷基氧呋喃的乙烯基类Mukaiyama aldol反应平稳地进行，从而以优异的收率得到了aldol产物，而没有非对映选择性的损失。在类似条件下，无环烯酮甲硅烷基缩醛也可作为对位阻酮的亲核试剂。这些发现表明，Tf 2 CHCH 2 CHTf 2 诱导的Mukaiyama aldol型反应可以克服反应位点之间的空间位阻。

  The concept of parallel recognition has been applied to differentiate between ketone and aldehyde: (C6F5)2SnBr2-catalyzed Mukaiyama-aldol reaction of a mixture of these two carbonyl substrates with a mixture of enol silyl ethers derived from esters and ketones results in exclusive formation of ketone/ester and aldehyde/ketone aldol adducts, respectively.

• Unusual Preference for Ketone and Reversal of Chemoselectivity in Lewis Acid-Catalyzed Aldol Reaction of Ketene Silyl Acetal

  Ketene silyl acetals undergo facile reaction with ketones in the presence of a Lewis acid such as (C6F5)(2)SnBr2, TMSOTf, or Sc(OTf)(3). This unique reactivity allows ketones to react in preference to aldehydes or acetals in competitive aldol-type reactions. Upon treatment with keto aldehydes or keto acetals, ketene silyl acetals provide single products derived from the exclusive reaction with the ketonic function. Particularly noteworthy is the discrimination of ketones from aldehydes in naked forms. It has been proved that such bias results from the differentiated recognition of ketone and aldehyde carbonyls. The ternary system consisting of ketene silyl acetal, carbonyl, and an appropriate Lewis acid is crucial for achieving the effective differentiation.
