各位化学同仁:
逝者如斯,岁末将至,2023年最后一期有机合成路线设计擂台赛已于近日落下帷幕。掩上过往的重门,回顾一年来的林林总总,想必不少人会颇有感慨:抑或满载而归,蓄势待发,抑或憾事未消,千头万绪。然往者不可谏,来者犹可追,宠辱得失,皆为序章。我们能做的,唯有以史为镜,把握当下,珍惜未来的每一次春种秋收。
化学技术部第一时间将本期的竞赛试题整理汇总,在此呈现给大家。文末附有往期试题,供君一览。秉承惯例,试题解析还将以网络直播的形式择时分享,敬请关注!
1. 请写出以下多步转化的产物结构(每题4分,共计20分; 相对构型需要标注明确)。Please provide the structures of products after multi-step transformations (20 points, 4 points for each question; the Relative Configuration needs to be clearly labeled).Please propose two reasonable synthetic routes to synthesize below target starting from commercially available reagents (20 points).3. 使用不同的关环策略设计两条路线合成以下化合物(20分)。 Please propose two reasonable synthetic routes to synthesize below target starting from commercially available reagents (20 points).Please propose two reasonable synthetic routes to synthesize below target starting from commercially available reagents (20 points).Please propose two reasonable synthetic route to synthesize below target starting from commercially available reagents (20 points).Please propose two reasonable synthetic route to synthesize below chiral target starting from commercially available reagents (20 points).感谢回顾往期竞赛试题及解析,如有任何建议,欢迎留言交流讨论!
