A Microwave-Assisted Diastereoselective Multicomponent Reaction To Access Dibenzo[c,e]azepinones: Synthesis and Biological Evaluation
摘要:
An unprecedented microwave-assisted multicomponent strategy has been elaborated for the fast, efficient, and diastereoselective generation of the dibenzo[c,e]azepinone scaffold. The generated compounds were evaluated for their bioactivity.
Total synthesis of plagiochins C and D, macrocyclic bis(bibenzyl) constituents of plagiochila acantophylla
摘要:
Plagiochins C (3) and D (4) were synthesized by convergent schemes. Rings C and B were joined by Ullman ether synthesis, the aryl-aryl bond between rings A and D was formed by Pd(0)-catalysed coupling of an arylboronic acid (ring D) and a bromobenzoic ester (ring A). Ring C and D were linked by the Wittig reaction, while final ring closure was effected by tetraphenylethene assisted Wurtz reaction.
