  Enone–Alkyne Reductive Coupling: A Versatile Entry to Substituted Pyrroles

  摘要：

  The reductive coupling of enones or enals with alkynes, followed by olefin oxidative cleavage and Paal-Knorr cyclization, provides a versatile entry to a variety of pyrrole frameworks. A number of limitations of alternate entries to the requisite 1,4-dicarbonyl intermediate are avoided. Classes of pyrroles that are accessible by this approach include 2,3-, 2,4-, 1,2,3-, 1,2,4-, 2,3,5-, and 1,2,3,5-substituted monocyclic pyrroles as well as a number of fused-ring polycyclic derivatives.

  The present invention relates to the preparation of compounds of the general formula II which can be obtained by 1,4 addition of 2-oxoalkanoates or 2-oxocarboxylic acids onto the appropriate ketones. The present invention also relates to the use of the PigD protein for catalysis of 1,4 additions of 2-oxoalkanoates/-carboxylic acids, for example pyruvate/pyruvic acid or 2-oxobutyrate/2-oxobutyric acid, onto aliphatic, aromatic and heterocyclic α,β-unsaturated ketones. The 1,4 additions are effected here with CO 2 elimination. The use of the PigD protein as a catalyst in the aforementioned 1,4 additions enables the synthesis of addition products with stereoactive centers these addition products being preparable with an enantiomeric excess of more than 80% ee. The aliphatic, aromatic and heterocyclic α,β-unsaturated ketones which are suitable for the process are represented by the general formula I:

  本发明涉及制备一般式II化合物的方法，该方法可以通过将2-氧代烷酸酯或2-氧代羧酸加成到适当的酮上来获得。本发明还涉及利用PigD蛋白催化2-氧代烷酸酯/羧酸的1,4加成，例如对丙酮酸/丙酮酸或2-氧丁酸/2-氧丁酸加成到脂肪族、芳香族和杂环α,β-不饱和酮上。这里的1,4加成是伴随着CO2消除进行的。在上述1,4加成中使用PigD蛋白作为催化剂，可以合成带有立体活性中心的加成产物，这些加成产物可以以超过80% ee的对映体过量制备。适用于该过程的脂肪族、芳香族和杂环α,β-不饱和酮由一般式I表示。

  A facile method for the intermolecular Stetter reaction of various Michael acceptors with acetaldehyde as a biomimetic acylanion source was realized using N-heterocyclic carbene catalysis. This catalytic system has also been applied to the enantioselective Stetter reaction and resulted in moderate to good enantioselectivities for the corresponding Stetter products.

  utilizing N-heterocyclic carbenes (NHCs) derived from thiazolium salts has been developed for the generation of carbonyl anions from acylsilanes. Synthetically useful 1,4-diketones and N-phosphinoyl-α-aminoketones have been prepared in good to excellent yields via NHC-catalyzed additions of acylsilanes to the corresponding α,β-unsaturated systems and N-phosphinoylimines. These organocatalytic reactions

  A new acyl anion addition reaction between acylsilanes and alpha,beta-unsaturated conjugate acceptors promoted by a nucleophilic organic catalyst has been disclosed. The 1,4-dicarbonyl products produced in this reaction are highly useful synthons. Neutral carbenes (or zwitterions) generated in situ from commercial thiazolium salts are used as effective catalysts for the reaction which is in contrast
