In the base-induced Peterson olefination of diastereomerically pure 8-methoxy-7-(trimethylsilyl)-6-tridecanol, anti pathway to eliminate a methoxide ion was found to compete significantly with amply precedented syn-elimination of a trimethylsilanolate ion. On the basis of an extent of the competing reactions which depend markedly on the respective diastereomers (three from four diastereomers) the detailed
在非对映体纯的8-甲氧基-7-(三甲基甲硅烷基)-6-十三烷醇的碱诱导的Peterson烯化中,发现消除甲氧根离子的抗途径与三甲基甲硅烷醇根离子的充分先行的顺式消除作用显着竞争。在其上显着地取决于相应非对映体(3从四个非对映体)的的详细机理的竞争反应的程度的基础上合成在剔除出现了。
