• Radical Addition of 2-Iodoalkanamide or 2-Iodoalkanoic Acid to Alkenes with a Water-Soluble Radical Initiator in Aqueous Media: Facile Synthesis of<i>γ</i>-Lactones

  Radical reactions in water or aqueous ethanol using a water-soluble radical initiator are described. Heating a mixture of 2-iodoacetamide and 5-hexen-1-ol in water at 75 °C in the presence of a water-soluble radical initiator, 4,4′-azobis(4-cyanopentanoic acid), afforded 5-(4-hydroxybutyl)dihydrofuran-2(3H)-one in 95% yield. The use of 2-iodoacetic acid in place of 2-iodoacetamide also gave the same γ-lactone in 93% yield. The reaction of 2-iodoacetamide with 1-octene in aqueous ethanol was initiated by 2,2′-azobis(2-methylpropanamidine) dihydrochloride to provide γ-decanolactone. Employing water as a solvent is crucial to obtain lactone in satisfactory yield.

  在水或含水乙醇中使用水溶性自由基引发剂的剧烈反应已有报道。将2-碘代乙酰胺和5-己烯-1-醇的混合物在75°C下加热，并加入水溶性自由基引发剂4,4′-偶氮双（4-氰基戊酸），可得到产率为95%的5-（4-羟基丁基）二氢呋喃-2（3H）-酮。使用2-碘代乙酸代替2-碘代乙酰胺也能以93%的产率得到相同的γ-内酯。在含水乙醇中，通过2,2′-偶氮双（2-甲基丙酰胺）二盐酸盐引发2-碘代乙酰胺与1-辛烯的反应，得到γ-癸醇内酯。使用水作为溶剂对于获得高产率的乳酮至关重要。
• Titanocene-Catalyzed Reduction of Lactones to Lactols

  DOI：10.1021/jo971560s

  日期：1997.11.1

  A convenient method for the conversion of lactones to lactols is described. The hydrosilylation to lactols is carried out via air-stable titanocene difluoride or a titanocene diphenoxide precatalyst using inexpensive polymethylhydrosiloxane (PMHS) as the stoichiometric reductant. These procedures have been demonstrated with a variety of substrates and proceed in good to excellent yield.

  描述了一种方便的将内酯转化为内酯的方法。使用便宜的聚甲基氢硅氧烷（PMHS）作为化学计量的还原剂，通过空气稳定的二茂钛二氟化物或二茂钛二苯醚预催化剂进行氢化硅烷化为乳糖醇。这些步骤已在多种底物上得到证明，并且以良好至极好的收率进行。
