developmentof new arylmethyl transfer (benzylation) reagents for protectingoxygen functional groups under relatively mild and neutral conditions.It begins with an investigation of organosiletanes as surrogatehydroxyl groups, which inspired siletane-functionalized benzyl ethersand forced us to confront the difficulties associated with the synthesisof benzyl ethers. The end result is a new series of neutral oxypyridiniumsalts
该帐户记录了导致开发新的芳甲基转移(苄基化)试剂在相对温和和中性条件下保护氧官能团的努力。它从作为替代羟基的有机硅酮的研究开始,它启发了硅烷官能化的苄基醚并迫使我们面对与苄基醚合成相关的困难。最终结果是一系列新的中性氧吡啶鎓盐,用于在温和条件下对各种亲核官能团进行苄基化。1 引言 2 应变有机硅烷的 Tamao 型氧化 3 P-Siletanylbenzyl (PSB) 保护基团 4 2-Benzyloxy-1-methylpyridinium Triflate 5 Friedel-Crafts 反应和机理洞察 6 苄酯形成 7 取代的 Benz8 转移试剂和展望
