A short and high yield synthetic route to novel dibenz[ B, G]oxonins, one of which has been characterized by X-ray crystallography, has been developed based on a sequential Baylis-Hillman reaction and radical cyclization. The regioselective radical cyclization followed a 9- ENDO- TRIG pathway.
基于连续的 Baylis-Hillman 反应和自由基环化,开发了一种短且高产率的新型二苯并 [B, G]oxonins 合成路线,其中一种已通过 X 射线晶体学进行了表征。区域选择性自由基环化遵循 9-ENDO-TRIG 途径。
