在可見光介導下,以脫碳方式,催化烯烴/炔烴/丙烯基與異氰化合物合成醯胺鍵。

Visible Light Mediated Amidation of Alkenyl / Alkynyl /Allyl Group with Isocyanides via Carbon Deletion

指導教授 : 王志鉦

摘要


在這個論文中,開發了一種新的、有效的、和溫和的合成策略,在TBHP / TBAI系統下將苯乙炔/苯乙烯/烯丙基苯與異氰化物構建醯胺衍生物。 該反應可能是通過異氰化物的逐步降解反應經自由基途徑下的醯胺化的替代方案。 顯著的特徵,如廣泛的官能基耐受性範圍、室溫、中等到良好的產率、在不含過渡金屬的情況下。 此外,這是一種光降解反應的新策略。

In this project, we have developed a novel, efficient and mild condition for amide bond construction from phenyl acetylene/styrene/allyl benzene and isocyanide in the presence of TBHP/TBAI as an oxidant under light condition. This protocol might be an alternative procedure for the amidation under the metal free via radical pathway from isocyanide with step down reaction. The notable features of this protocol are carbon deletion, broad substrate scope, mild condition, visible light, and metal free. Moreover, this is a new tactics for the synthesis of amide bond from Alkyne/Alkene/Allyl group with Isocyanides via carbon deletion strategy in the presence of visible light.
