• Synthesis of (R)- and (R)-4-methyl-6-2?-methylprop-1?-enyl-5,6-dihydro-2H-pyran (Nerol oxide) and Natural Occurrence of its Racemate

  3-epoxy-citronellols (5) was prepared from (−)-(R)-linalool (3) via epoxy alcohol 4 and then reduced to (−)-(R)-3-hydroxy-citronellol (6). Sensitized photooxygenation of (−)-(R)-diol 6 led in part to (−)-(R)-triol 8 which was cyclodehydrated by dilute acid to a mixture of diastereoisomeric tetrahydropyran-4-ols 9 and 10. Dehydration of hydroxy ethers 9 and 10 afforded (−)-(S)-nerol oxide (11) and (+)-(R)-nerol

  按照已知方法，由（-）-制备（-）-（2 S，3 R）-和（+）-（2 R，3 R）-2,3-环氧香茅酚（5）的混合物。（R）-芳樟醇（3）通过环氧醇4，然后还原为（-）-（R）-3-羟基-香茅醇（6）。（-）-（R）-二醇6的敏化光氧化部分导致（-）-（R）-三醇8，后者被稀酸环化脱水成非对映异构体四氢吡喃-4-醇9和10的混合物。羟基醚9和10的脱水分别得到（-）-（S）-氧化新戊二醇（11）和（+）-（R）-氧化新戊二醇（12），光学纯度为91％。从保加利亚玫瑰油中分离出的氧化氮（0.038％）被证明是外消旋的。这些结果为植物中氧化神经醇的形成提供了一些启示。

  In a screening program of natural compounds from fungi, the known cyclopentanoid sesquiterpene (−)-cyclonerodiol was identified as a specific inhibitor of the IL-4 induced STAT6 signaling pathway (IC50 = 9.7 μM) which is required for the differentiation of naive CD4 T cells to T helper type 2 (Th2) lymphocytes. As many allergic conditions, including allergic asthma and atopic diseases, are driven by

  在真菌天然化合物的筛选程序中，已知的环戊烷倍半萜（-）-环神经二醇被鉴定为IL-4诱导的STAT6信号通路的特异性抑制剂（IC 50 = 9.7μM），这是幼稚CD4分化所必需的T细胞至T辅助2型（Th2）淋巴细胞。由于过度的Th2反应导致许多过敏性疾病，包括过敏性哮喘和特应性疾病，因此STAT6是开发新疗法的有希望的目标。使用环氧自由基环化作为关键步骤，从（-）-芳樟醇分六步合成了该化合物。

  A protecting-group-free synthesis of two endoperoxide natural products, plakortolide E and plakortolide I, is reported. Key steps are a vanadium-mediated epoxidation, an iron-catalyzed allylic substitution, and a cobalt-induced endoperoxide formation. Our approach combines chemoselective bond-forming reactions and one-pot operations to forge an overall efficient synthesis.

  As a result of a combined theoretical and experimental study, we describe a two-step protocol for the preparation of an optically pure, multifunctional, cyclopentanic core shared by a number of natural products. This process is based on a hitherto unreported Ti(III)-mediated diastereoselective cyclization in which the hydroxy-directed template effect played by the Ti(III) species was found to be crucial for the stereoselective outcome of the reaction. The viability of this concept was confirmed with the first protecting-group free synthesis of three enantiopure chokols, namely, chokols K, E, and B.
