novel and highly efficient copper‐catalyzed tandem synthesis of triazoloquinazolinones is explored. The synthetic strategy involves a sequential one‐pot click reaction followed by aerobic intramolecularCHamidation. Two distinct and important transformations were carried out in one‐pot by employing a single cost‐effective copper catalyst. The milder, rapid and ligand‐free reaction conditions as well

An efficient preparation of fused [2,1-b]quinazolinones has been developed utilizing polymer-supported reagents. (±)-Vasicinone was converted into its dione by oxidation with poly (4-vinylpyridiniumdichromate). An efficient method has been developed for the synthesis of (d)- and (l)-vasicinone via asymmetric reduction of pyrrolo[2,l-b]quinazoline-3,9-dione by employing NaBH 4 /Me 3 SiCl as the reducing

This paper reports the tandemreaction strategy of the Passerini/Staudinger/aza-Wittig reaction based on the in situ capture of isocyanides. According to this strategy, isocyanides are synthesized in situ and immediately work as the substrate for the Passerini reaction and postmodification tandemreaction in one pot. In addition, two types of new compounds, 5-oxo-3,5-dihydrobenzo[e][1,4]oxazepines
本文基于异氰酸酯的原位捕获,报道了Passerini / Staudinger / aza-Wittig反应的串联反应策略。根据这一策略,异氰化物可在原位合成,并立即用作一罐中Passerini反应和后修饰串联反应的底物。此外,还使用以下方法合成了两种新型化合物:5-氧代-3,5-二氢苯并[ e ] [1,4]氧氮杂卓和6-氧代-5,6-二氢-2 H -1,4-恶嗪。一站式反应策略,其中包括五步转化。
