• Highly pH-Dependent Chemoselective Transfer Hydrogenation of α,β-Unsaturated Aldehydes in Water

  electron-poor substituents on the aryl group of α,β-unsaturated aldehydes can be tolerated, affording the corresponding products in excellent yields with high TOF values. High selectivity and yields were also observed for α,β-unsaturated aldehydes with aliphatic substituents. Our mechanistic investigations indicate that the pH value is critical to the chemoselectivity.

  在水中实现了pH依赖的选择性Ir催化的α，β-不饱和醛的加氢反应。在低pH下使用HCOOH作为氢化物供体，仅获得不饱和醇产物，而在高pH下，优先使用HCOONa作为氢化物供体形成饱和醇产物。可以耐受包括α，β-不饱和醛的芳基上的富电子以及贫电子取代基在内的各种官能团，从而以高收率提供具有高收率的相应产物。还观察到具有脂族取代基的α，β-不饱和醛的高选择性和产率。我们的机理研究表明，pH值对化学选择性至关重要。
• Kinetic resolution of primary 2-methyl-substituted alcohols via Pseudomonas cepacia lipase-catalysed enantioselective acylation

  日期：——

  The enantioselectivities of lipases from Pseudomonas cepacia (PFL, Amano PS, etc.) towards a series of primary 2-methyl-substituted alcohols using vinyl acetate as the acyl donor in transesterifications in organic solvents were studied. In terms of enantioselectivity, the best results were found for 3-aryl-2-methylpropan-1-ols with enantiomeric ratios (E-values) over 100 in most cases, whereas other 3-substituted primary 2-methylpropan-1-ols generally displayed lower enantioselectivities: 3-cycloalkyl-2-methylpropan-1-ols (E ≈ 20) and 2-methylalkan-1-ols (E ≈ 10). Moving the aryl group closer or further away from the chiral centre resulted in low enantioselectivities: 2-arylpropan-1-ols (E < 10), 2-methyl-4-(2-thienyl)butan-1-ol (E = 12), 2-methyl-5-(2-thienyl)pentan-1-ol (E = 3.2) and 2-methyl-6-(2-thienyl)hexan-1-ol (E = 3.8).

  研究了来自洋葱伯克霍尔德菌（Pseudomonas cepacia）的脂肪酶（如PFL、Amano PS等）在对一系列一级2-甲基取代醇使用乙酸乙烯酯作为酰基供体进行有机溶剂中的转酯化反应时的对映选择性。在对映选择性方面，最佳结果出现在3-芳基-2-甲基丙-1-醇中，大多数情况下对映体比例（E值）超过100，而其他3-取代的一级2-甲基丙-1-醇通常显示出较低的对映选择性：3-环烷基-2-甲基丙-1-醇（E ≈ 20）和2-甲基烷-1-醇（E ≈ 10）。将芳基团更靠近或远离手性中心会导致低对映选择性：2-芳基丙-1-醇（E < 10）、2-甲基-4-（2-噻吩基）丁-1-醇（E = 12）、2-甲基-5-（2-噻吩基）戊-1-醇（E = 3.2）和2-甲基-6-（2-噻吩基）己-1-醇（E = 3.8）。
