  Sex Pheromone of the Pine Sawfly, Macrodiprion nemoralis. Stereoselective Synthesis of the Sixteen Stereoisomers of 3,7,9-Trimethyl-2-tridecyl Acetate.

  摘要：

  The sixteen stereoisomers of 3,7,9-trimethyl-2-tridecyl acetate (5Ac) were prepared individually, each in over 99.5% stereochemical purity. The syntheses were based on the ring opening of a pure enantiomer of cis-3,4-dimethyl-gamma-butyrolactone using a pure stereoisomer of 1-lithio-2,4-dimethyloctane, the two stereogenic centres of which were introduced with high selectivity by alkylations of the amide enolates from the appropriate enantiomers of pseudoephedrine. (2S,3R,7R,9S)-3,7,9-Trimethyl-2-tridecyl acetate (SRRS-5Ac) has recently been found to be the major component of the female sex pheromone of Macrodiprion nemoralis (Hymenoptera: Diprionidae). A synthetic method for the preparation of a sixteen isomer mixture of 5Ac is also presented. This mixture has been found to be biologically active in field tests.

• A General Strategy for the Introduction of Stereogenic Centers Bearing a Methyl Group: Total Synthesis of Sex Pheromones

  日期：2011.2.1

  We're bringing sexy back: The highly efficient introduction of stereogenic centers bearing methyl group by conjugate addition of RMgBr to α,β‐unsaturated esters has been employed in the total syntheses of two sex pheromones (see scheme). Binap=[1,1′‐binaphthalene]‐2,2′‐diylbis(diphenylphosphane).

  我们正带回性感：通过将RMgBr共轭加到α，β-不饱和酯中来高效引入带有甲基的立体异构中心已被用于两个性信息素的总合成中（参见方案）。Binap = [1,1'-联萘] -2,2'-二基双（二苯基膦）。

  paper presents a new approach to the preparation of enantiomerically pure (2S,3R)-3-methylalkan-2-ols, the esters of which are sex pheromones of several pine sawflies. Thus, an asymmetric 1,3-dipolar cycloaddition between a sulfur containing 1,3-dipole and a dipolarophile attached to (1R)-camphorsultam containing a vinyl ether functionality furnished a 90 : 10 diastereomeric mixture of trans-3,4-disubstituted

  本文提出了一种制备对映体纯 (2S,3R)-3-methylalkan-2-ols 的新方法，其酯类是几种松叶蜂的性信息素。因此，含硫的 1,3-偶极子和连接到含有乙烯基醚官能团的 (1R)-樟脑磺胺的亲偶极试剂之间的不对称 1,3-偶极环加成反应提供了 90:10 的反式 3,4-二取代四氢噻吩的非对映异构体混合物酰胺。主要的转化为对映体纯的四氢噻吩基甲基溴，其与单烷基化二噻烷单元偶联。经雷尼镍还原(2S,3R,7R,9S)-3,7,9-trimethyltridecan-2-ol，其乙酸酯即为Macrodiprion nemoralis的引诱性信息素成分。
