A new and competitive synthesis of bicyclo[n.1.0]trimethylsilanes is reported, involving a facile and rapid process, and giving both endo and exo isomers. The behavior of these species towards acids (HCl, (AcOH)2BF3) has been investigated. The stereochemistry of the substrate does not influence the regiochemistry of the electrophilic attack, while the stereochemistry of the largest ring plays a decisive
双环的新和竞争合成[ Ñ .1.0]三甲基硅烷报道,涉及容易且快速的过程,并给予两个内切和外切异构体。已经研究了这些物质对酸(HCl,(AcOH)2 BF 3)的行为。底物的立体化学不影响亲电攻击的区域化学,而最大环的立体化学起决定性作用。观察到环丙烷环的开环,如果它被结合到一个五元或六元环,而CSiMe 3如果它与八元环键合,则会发生裂解。结果揭示了通过环丙烷化对环烯烃进行官能化的新观点。
