Introducing a silyl group at one of the internal olefin positions in diolefinic substrates results in E-selective olefin formation in macrocyclic ring-forming metathesis. The application of this method to a range of macrocyclic (E)-alkenylsiloxanes is described. Protodesilylation of alkenylsiloxane products yields novel Z-configured macrocycles. 相似文献

2-(2-Methoxyethoxy)-toluene and 2-(2-dimethylaminoethoxy)-toluene have been lithiated using sec-BuLi under a variety of conditions and the laterally lithiated species trapped with electrophiles, including but-1-ene oxide, leading to a new synthesis of 2-ethylchroman. 相似文献
