  Total Synthesis of Papulacandin D

  摘要：

  A total synthesis of the antifungal agent papulacandin D is reported. The molecule is representative of a large class of C-aryl glycosides that exhibit significant antifungal activity. The synthetic strategy bifurcates the molecule into two nearly equal subunits, the arylglycoside and 18-carbon fatty acid side chain. The key strategic transformations are (1) the palladium catalyzed, organosilanolate-based cross-coupling of a protected glucal silanol and (2) a catalytic enantioselective allylation of a dienal using allyltrichlorosilane. The synthesis was accomplished in 31 steps overall from commercial starting materials to afford over 50 mg of the natural product.

• Chiral Discrimination of Cryptochiral Saturated Quaternary and Tertiary Hydrocarbons by Asymmetric Autocatalysis

  Chiral discrimination of saturated hydrocarbons has been very difficult to establish, or has not been possible at all. The first chiral discrimination of cryptochiral 5-ethyl-5-propylundecane 1, that is, (n-butyl)ethyl(n-hexyl)(n-propyl)methane, a chiral saturated quaternary hydrocarbon, which is known to exhibit practically no detectable value of optical rotation between 280 and 580 nm, has been accomplished

  饱和烃的手性区分很难建立，或者根本不可能。隐手性 5-乙基-5-丙基十一烷 1 的首次手性鉴别，即（正丁基）乙基（正己基）（正丙基）甲烷，一种手性饱和季烃，已知几乎没有检测到280 和 580 nm 之间的旋光度值是通过嘧啶基烷醇的不对称自催化实现的。1 的绝对构型已确定。在(R)-或(S)-1存在下，嘧啶-5-甲醛和二异丙基锌之间的反应分别提供具有91-97％ee的(S)-和(R)-嘧啶基链烷醇。因此，不对称自催化是饱和烃手性鉴别的有力工具。

  Novel stereoisomeric indole compounds of the formula (1), a process for the preparation the same, and use thereof wherein, Y represents the group wherein, X represents alkyl group having 1-5 carbon atom(s) (the alkyl group may be substituted with hydroxyl group, carboxyl group, amino group, methylthio group, mercapto group, guanidyl group, imidazolyl group or benzyl group), and R1 and R2 represent each independently hydrogen atom, alkyl group, aralkyl group, cycloalkyl group or aryl group;R represents hydrogen atom, alkyl group, aralkyl group, cycloalkyl group, aryl group, monovalent metal, amine or ammonium; and the symbol ‘*’ represents a position of an asymmetric carbon atom. The above-mentioned compounds can be prepared by condensing tryptophan with a stereoisomeric &agr;-amino acid or carboxylic acid to form an amide form and subjecting or carboxylic acid to form an amide form and subjecting the amide form to oxidative cyclization to form an oxazole ring at once. The compounds exhibit; physiological activities such as inhibitory action against lipid peroxidation, and can be therefore utilized in the form of lipid peroxidation inhibitors containing the same as the active ingredient.

  新颖的立体异构吲哚化合物的化学式（1），其制备方法及用途，其中，Y代表的是该组，X代表具有1-5个碳原子的烷基（该烷基可以被羟基、羧基、氨基、甲硫基、巯基、胍基、咪唑基或苄基取代），R1和R2各自独立地代表氢原子、烷基、芳基、环烷基或芳基；R代表氢原子、烷基、芳基、环烷基、芳基、一价金属、胺或铵；符号‘*’代表不对称碳原子的位置。上述化合物可通过将色氨酸与立体异构的α-氨基酸或羧酸缩合形成酰胺形式，再将酰胺形式氧化环化一次形成噁唑环来制备。这些化合物表现出生理活性，如对脂质过氧化的抑制作用，因此可以作为含有其作为活性成分的脂质过氧化抑制剂而被利用。

  The first total synthesis of martefragin A, a potent inhibitor of lipid peroxidation isolated from sea alga, has been accomplished and the absolute configurations of two stereogenic centers were determined. Synthetic martefragin A, its stereo isomers, and some analogs showed strong inhibitory activity against lipid peroxidation using rat liver microsome.

  (2E,4E,6R,10S)-4,6,10-Trimethyl-2,4-dodecadien-7-one 1 and its (6S,10S)-isomer were synthesized. The H-1 NMR spectrum of (6S,10S)-1 coincided with that reported for the major component of the sex pheromone of Matsucoccus feytaudi, which must therefore be either (6S,10S)- or (6R,10R)-1.

  (2E,4E,6R,10S)-4,6,10-三甲基-2,4-十二碳二烯-7-酮 1 及其 (6S,10S)-异构体被合成。 (6S,10S)-1 的 H-1 NMR 谱与松突圆蚧 Matsucoccus feytaudi 性信息素主要成分的报告相符，因此该物质必定是 (6S,10S)-或 (6R,10R)-1。
