有机合成双语20段翻译1-------页码6The relationship between functional groups may provide the clue to a particular strategy (e.g. a β-hydroxy ketone may imply an aldol condensation). As you learn a synthetic reaction, note the relationslip that is involved between: (i) the activating group that generates the reactive species, (ii) the new bond that is formed and (iii} the structural fate of the recipient group which is attacked by the reactives.The presence of electron-donating or elactron-withdrawing groups may favour particular reactions at particular centres. For example, this is very important in aromatic substitution, As you learn a synthetic sequence, note the influence of the factors such as resonance that may favour regions of electron density or deficiency.官能团之间的关系可能给一种特殊的策略提供线索(例如α,β-羟基酮结构可能表明一种羟醛缩合)。
当你学到一种合成反应时,应该关注其中包含的这些关系:(i)决定反应类型的活性官能团,(ii)新键的形成和(iii)被反应物质攻击的官能团最终的结构。
