  Palladium-Catalyzed Stereoconvergent Formylation of (E/Z)-β-Bromo-β-fluorostyrenes: Straightforward Access to (Z)-α-Fluorocinnamic Aldehydes and (Z)-β-Fluorocinnamic Alcohols

  摘要：

  We report here the stereoconvergent formylation of (E/Z)-beta-bromo-beta-fluorostyrene mixtures with carbon monoxide and sodium formate catalyzed by palladium. Optimization of reaction conditions leads to the corresponding pure (Z)-alpha-fluorocinnamaldehydes in good yields. The reaction was extended to styrenes bearing electro-attracting or electro-donating groups. The obtained alpha-fluoroaldehydes were smoothly reduced to the corresponding (Z)-beta-fluorocinnamic alcohol by NaBH4. The reaction could be performed on functionalized substrates as demonstrated by the access to the glucoside of beta-fluoroconiferyl alcohol, (Z)-beta-fluoroconiferin, a strong inhibitor of lignin polymerization.

  of α,β-unsaturated aldehydes to their corresponding (Z)-α-fluoro-α,β-unsaturated aldehydes has been developed. The first step utilises Selectfluor as a fluorinating agent in CH3NO2/MeOH forming (Z)-α-fluoro-α,β-unsaturated aldehydes and their corresponding dimethyl acetals via methoxyfluorination-elimination. In the second step, water is added to promote the hydrolytic cleavage of the dimethyl acetals

The α-fluorothioesters were obtained in a good yield by condensing the aldehydes with the lithium anion of

  我们描述了一种仿生方法（Z）-β-氟代烯丙醇，其基于霍纳-沃兹沃思-埃蒙斯与2-（二乙氧基膦基）-2-氟代-乙硫基酸S的芳香醛到α-氟代肉桂酸酯的两个碳同系物-乙基酯，然后在温和条件下用硼氢化钠还原。通过将醛与2-（二乙氧基膦基）-2-氟-乙硫酸锂，S-乙酯的锂阴离子在-78°C的THF中缩合，可以以高收率获得α-氟代硫酯。然后将（E，Z）-α-氟肉桂酸硫代酯混合物通过双键异构化通过NaBH 4干净地还原为相应的（Z）-β-氟烯丙基醇在室温下。该方法可以应用于高度官能化的醛，例如可以直接获得（Z）-β-氟松柏油，这是一种从O-糖基化香兰素木质素聚合的强抑制剂。
