[求助] 大神求帮忙翻译

第一篇:A synthetic approach to paxilline indole diterpenes is described. The route to the pentacyclic core relies on a new regioselective alkenylation of ketones and a tandem radical addition–aldol reaction sequence to access vicinal quaternary stereocenters. Emindole SB, the simplest member of the family, is synthesized in 11 steps from commercially available material to demonstrate the application of this approach。
第二篇:The selective preparation of 1,1,1-tris(boronates) from vinylarenes and bis(pinacolato)diboron is described. The reactions occur at ambient temperature with excellent selectivity, high yields, and good functional group tolerance. Mechanistic studies suggest that Co(I)-catalyzed double dehydrogenative borylations generate a 1,1-diborylalkene intermediate, which undergoes hydroboration with pinacolborane formed in situ to yield 1,1,1-tris(boronate).

本文研究了用vinylarenes和bis(pinacolato)diboron选择性制备1,1,1-tris(boronates)的方法。该反应在室温下具有高选择性、高产率及良好的官能团稳定性。机理研究表明Co(l)催化的double dehydrogenative borylations反应过程中产生了1,1-diborylalkene 中间体,它与原位生成的pinacolborane发生硼氢化反应生成了1,1,1-tris(boronate).     外行  专业词汇搞不定

谢谢了,我也是几个关键的专业词汇不会了,,看来以后要更努力了,不知你有什么方法可以提高翻译此类文章的能力
