  The synthesis of the insect pheromone (2S,3R,7R)-3,7-dimethyltridec-2-yl acetate from racemic 3,4-dimethyl-γ-butyrolactone by diastereoselective chiral resolution

  摘要：

  The insect pheromone (2S,3R,7R)-3,7-dimethyltridec-2-yl acetate 1-Ac was prepared from diastereomerically enriched (2S*,3R*,7R)-1, which in turn was obtained by the coupling of racemic 3,4-dimethyl-gamma-butyrolactone with (7S)-2-methyloctyllithium, followed by a Wolff-Kishner reduction of the resulting ketone. Conversion of (2S*,3R*,7R)-1 to the corresponding alkyl hydrogen phthalate and diastereomer salt formation with (S)-PhCHMeNH2 provided after several crystallizations individual diastereomer, which was later transformed into target 1-Ac after hydrolysis and acylation.

  A highly versatile and efficient hydrosilylation method by palladium nanoparticle catalysis allows the direct and chemoselective synthesis of 1) enolsilanes of high isomeric purity, 2) saturated aldehydes or ketones, or 3) the corresponding saturated acetals from α,β‐unsaturated aldehydes or ketones. The choice of the product is determined by simply switching the solvent from THF to mixtures of THF/water

  An alkoxide-catalyzed directed diboration of alkenyl alcohols is described. This reaction occurs in a stereoselective fashion and is demonstrated with cyclic and acyclic homoallylic and bishomoallylic alcohol substrates. After oxidation, the reaction generates 1,2-diols such that the process represents a method for the stereoselective directed dihydroxylation of alkenes.

  描述了烯醇的醇盐催化的定向二硼化。该反应以立体选择性方式发生，并用环状和非环状均烯丙基醇和双烯丙基醇底物证明。氧化后，反应生成 1,2-二醇，因此该过程代表了烯烃立体选择性定向二羟基化的方法。

A simple and efficient protocol for the transformation of a wide range of sterically hindered α- and β-substituted aliphatic aldehydes/enals, catalyzed by a novel and readily accessible N-Mes-/N-2,4,6-trichlorophenyl 1,2,4-triazolium salt, and benzoic acid as co-catalyst
