, p. 9092 - 9094,3 (2020/08/31)
A new and convergent synthesis of ascididemin is presented. Using an anionic cascade ring closure as the key step, this natural product is obtained in 45% overall yield in just 6 steps starting from 2′-fluoroacetophenone. This new approach was extended to the synthesis of a new isomer of ascididemin.
Synthesis of azaphenanthridines via anionic ring closure
Hansen, Henriette M.,Lysén, Morten,Begtrup, Mikael,Kristensen, Jesper L.
, p. 9955 - 9960 (2007/10/03)
A new and convergent synthesis of azaphenanthridines via an anionic ring closure is reported. Ortho-lithiation/in situ borylation of cyanopyridines produces the corresponding cyanopyridylboronic esters, which undergo a Suzuki-Miyaura cross-coupling to giv
