  烯丙基溴存在下PdCl2 / FeCl3共催化的2,3-烯丙基酯偶联环的有机铁

  摘要：

  新的偶合：氯化铁与2,3-烯丙基甲酸酯的相互作用产生了2-（5 H）-呋喃基铁物种，据观察该物种很容易与PdCl 2发生金属转移，从而导致与烯丙基溴的偶合（参见方案）。基于该反应，已经开发了一种有效的方法，可以通过使用廉价易得的FeCl 3作为PdCl 2的助催化剂，从容易获得的烯丙基溴和2,3-烯丙基酯合成β-烯丙基多取代的丁烯内酯。

• Ferric Chloride Hexahydrate-Catalyzed Highly Regio- and Stereoselective Conjugate Addition Reaction of 2,3-Allenoates with Grignard Reagents: An Efficient Synthesis of β,γ-Alkenoates

  DOI：10.1002/adsc.200900091

  日期：2009.8

  Ferric chloride hexahydrate was shown to be an efficient catalyst for the conjugate addition of 2,3-allenoates with alkyl-, aryl-, or vinyl-Grignard reagents to synthesize polysubstituted β,γ-unsaturated alkenoates with high regio- and stereoselectivity. The in situ formed magnesium dienolate may readily react with different electrophilic reagents under different reaction conditions with or without

• Study on the selectivity in the electrophilic monofluorination of 2,3-allenoates with Selectfluor™: an efficient synthesis of 4-fluoro-2(5H)-furanones and 3-fluoro-4-oxo-2(E)-alkenoates

  Different from the reaction of 2,3-allenoic acids with Selectfluor™, 4-fluoro-2(5H)-furanones and (E)-3-fluoro-4-oxo-2-alkenoates were highly selectively generated from 2,4-disubstituted 2,3-allenoates with Selectfluor™ under different conditions in moderate yields. The reaction of 2,4,4-trisubstituted 2,3-allenoates afforded the corresponding 4-fluoro-2(5H)-furanones highly selectively with up to 95% yield under different conditions. The scope of the substrates has been carefully explored. Due to the more readily availability of 2,3-allenoates as compared to 2,3-allenoic acids, new 4-fluoro-2(5H)-furanones were prepared. Based on the isolation and characterization of the minor fluorohydroxylation product E-5m, a mechanism has been proposed.

  与2,3-烯酸与Selectfluor™反应不同，在不同条件下，2,4-取代的2,3-烯酸酯与Selectfluor™反应，能够高选择性地生成4-氟-2(5H)-呋喃酮和(E)-3-氟-4-氧代-2-烯酸酯，产率适中。2,4,4-三取代的2,3-烯酸酯的反应在不同条件下高选择性地生成相应的4-氟-2(5H)-呋喃酮，产率高达95%。对底物的范围进行了仔细探讨。由于与2,3-烯酸相比，2,3-烯酸酯更易获得，因此合成了新的4-氟-2(5H)-呋喃酮。基于小量氟羟基化产物E-5m的分离和表征，提出了一种机制。

  butanol derivatives (6a—j, 12, 13, 15, 17, 24b,c, 26, 27a,b) were prepared from the readily available resorcinol derivatives 2a—f and 7‐hydroxy‐chroman (18). The products were tested for inhibitory activity on the LPS‐induced TNF‐α production in the plasma in comparison with that of cabenegrin A‐I (1a).

  日期：2024.6.21

  Photoinduced cyclization of 2,3-allenoic acids with sulfonyl chloride providing an efficient synthesis of 4-sulfonylated furan-2(5H)-ones under mild reaction conditions has been achieved. The reaction enjoys a high chemoselectivity and tolerates a wide range of functional groups. The catalytic cycle has been validated through control experiments, cyclic voltammetry studies, and Stern–Volmer quenching
