• The Botrytis cinerea type III polyketide synthase shows unprecedented high catalytic efficiency toward long chain acyl-CoAs
  作者：Marimuthu Jeya、Tae-Su Kim、Manish Kumar Tiwari、Jinglin Li、Huimin Zhao、Jung-Kul Lee

  BPKS from Botrytis cinerea is a novel type III polyketide synthase that accepts C4–C18 aliphatic acyl-CoAs and benzoyl-CoA as the starters to form pyrones, resorcylic acids and resorcinols through sequential condensation with malonyl-CoA. The catalytic efficiency (kcat/Km) of BPKS was 2.8 × 105 s−1 M−1 for palmitoyl-CoA, the highest ever reported. Substrate docking analyses addressed the unique features of BPKS such as its high activity and high specificity toward long chain acyl-CoAs.

  葡萄孢菌（Botrytis cinerea）中的BPKS是一种新型III型聚酮合酶，能够接受C4-C18的脂肪酰辅酶A和苯甲酰辅酶A作为起始物，通过与丙二酰辅酶A的连续缩合反应形成吡喃酮、间苯二酚酸和间苯二酚。BPKS对棕榈酰辅酶A的催化效率（kcat/Km）高达2.8 × 10^5 s^-1 M^-1，是有史以来报道的最高值。底物对接分析揭示了BPKS独特的特性，如其对长链酰基辅酶A的高活性和高特异性。

• Total Synthesis of Neurymenolide A Based on a Gold-Catalyzed Synthesis of 4-Hydroxy-2-pyrones
  作者：Wojciech Chaładaj、Matthieu Corbet、Alois Fürstner

  日期：2012.7.9

  Treat me gently: For a selective synthesis of the unusually sensitive cyclophanic α‐pyrone neurymenolide A, the chosen catalysts must be able to distinguish between six different sites of unsaturation, without scrambling any of the skipped π systems. This challenge was met with a new gold‐catalyzed pyrone synthesis in combination with a molybdenum‐catalyzed ring‐closing alkyne metathesis.

  温和地对待我：为选择性合成异常灵敏的α-吡喃酮神经节烯内酯A，所选的催化剂必须能够区分六个不同的不饱和位点，而不会扰乱任何跳过的π系统。新的金催化的吡喃酮合成与钼催化的闭环炔烃复分解反应解决了这一难题。
• Synthesis of the bis-potassium salts of 5-hydroxy-3-oxopent-4-enoic acids and their use for the efficient preparation of 4-hydroxy-2H-pyran-2-ones and other heterocycles

  5-Hydroxy-3-oxopent-4-enoic acid esters can be efficiently transformed into the stable bis-potassium salts of the corresponding 5-hydroxy-3-oxopent-4-enoic acids, from which the sensitive acids are released in situ, the latter being converted into substituted 4-hydroxy-2H-pyran-2-ones, pyrazoles and isoxazoles under mild conditions; the efficiency of this method is demonstrated by the first synthesis

  可以将5-羟基-3-oxopent-4-enoic酸酯有效地转化为相应的5-hydroxy-3-oxopent-4-enoic酸的稳定双钾盐，敏感酸从该盐中就地释放出来，后者在温和条件下转化为取代的4-羟基-2H-吡喃-2-酮，吡唑和异恶唑；该方法的效率通过两种天然存在的吡喃酮的首次合成得到证明。
