  Convenient Formation of 4-Hydroxyalk-2-en-1-one Functionality via A Knoevenagel-type Carbon Chain Elongation Reaction of Aldehyde with 1-Arylsulfinylalkan-2-one

  摘要：

  A highly functionalized four-carbon unit, 4-hydroxyalk-2-en-1-one functionality [(RCH)-C-2(OH)CH=CHCOR1], was conveniently prepared by a reaction of an aldehyde ((RCH2CHO)-C-2) with a 1-(arylsulfinyl)alkan-2-one [ArS(O)CH2COR1] in the presence of diethylamine (Knoevenagel condition). Other functional groups, such as carbonyl and hydroxy groups, in both of the alkyl chains (R-1, R-2) did not prevent this reaction. This reaction was used to conveniently prepare (+/-)-(11E)-13-hydroxy-10-oxooctadec-11-enoic acid (14), having cytotoxic activity, and its analogues from undec-10-enoic acid in good yield.

  不饱和酸和二氧化碳高效合成环状碳酸酯及其在生物基聚氨酯合成中的应用

  摘要：

  生物衍生的呋喃和二酸衍生的环状碳酸酯已经由末端环氧化物和 CO 2以高产率合成。此外，在某些情况下，以良好的收率和出色的非对映选择性分离了四种高度取代的萜烯衍生环状碳酸酯。在温和的反应条件下，由 10-十一碳烯酸衍生制备了 11 种新的环状碳酸酯，以优异的收率提供了相应的碳酸酯产品。该催化剂体系还在相对温和的反应条件（80°C，20 bar，24 小时）下将环氧化脂肪酸正戊酯转化为环状碳酸酯。这种双（环状碳酸酯）以高产率和不同的顺式/反式获得比例取决于所用的助催化剂。当双（三苯基膦）亚胺氯化物用作助催化剂时，仅观察到烯丙醇副产物作为次要产物。最后，使用两种环状碳酸酯作为结构单元，通过与 1,4-二氨基丁烷反应制备非异氰酸酯聚（羟基）氨基甲酸酯。

  Alkyltitanium alkoxides generally serve as nucleophiles in reactions with carbonyl compounds and cross-coupling. Their application as reductants is known but remains underdeveloped. Here, we report that irradiation with visible light makes these organometallic compounds efficient reducing agents for the dehalogenation of 1,2- and 1,3-haloalcohols. This reaction was utilized for the reduction of epoxides

  烷基钛醇盐通常在与羰基化合物的反应和交叉偶联中充当亲核试剂。它们作为还原剂的应用是已知的，但仍未得到开发。在这里，我们报告可见光照射使这些有机金属化合物成为 1,2- 和 1,3- 卤代醇脱卤的有效还原剂。该反应用于环氧化物和磺酸盐的还原，该反应通过一系列原位卤代醇形成和光化学脱卤进行。酯、酰胺、腈、炔和远程溴基团在反应条件下是稳定的。

  Novel epithio compounds from alkyl epoxy undecanoates (n-alkyl, C-1, C-4, and C-6; isoalkyl, C-3, C-4, and C-8) were synthesized using an ammonium thiocyanate in ionic liquid 1-methylimidazolium tetrafluoroborate/H2O (2:1) solvent system in 8590% yields by gas chromatographic (GC) analysis. The synthesized products were characterized by H-1 and C-13 nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy (FTIR), gas chromatography, and GC mass spectral (GC-MS) analyses and evaluated for their antioxidant, extreme pressure (EP), and antiwear (AW) properties in three different base oils, namely, epoxy jatropha fatty acid n-butyl esters (EJB), di-2-ethylhexyl sebacate (DOS), and mineral oil (S-105). Among the synthesized products, n-butyl epithio undecanoate exhibited superior antioxidant property (229.2 degrees C) compared to butylated hydroxytoluene (BHT, 193.8 degrees C) in base oil DOS and comparable performance in EJB and S-105 base oils. All of the epithio derivatives exhibited significantly enhanced weld point for the base oils EJB and DOS at 2 wt % level and displayed moderate enhancement in S-105 base oil. Methyl epithio undecanoate at 0.6% concentration exhibited considerable improvement in the wear scar of DOS base oil. The synthesized epithio derivatives have potential as multifunctional additives in lubricant formulations.
