参考标题:Visible Light-Mediated Coupling Of Thioureas And 1,3-Dicarbonyls: Towards A Leaving Group-Free Synthesis Of Aminothiazoles 作者:Irwan Iskandar Roslan,Kian-Hong Ng,Mohammed Ashraf Gondal,Chanbasha Basheer,Mohamed A. Dastageer,Stephan Jaenicke,Gaik-Khuan Chuah |发布日期:2018.4.17 摘要:A Synthesis Of Aminothiazoles From Various 1,3‐dicarbonyls And Thioureas Without A Leaving Group Has Been Developed. The Reaction Is Photocatalyzed By Tetraiodofluorescein, An Organic Dye. Under Irradiation With Green Leds, A Sulfur Radical Is Generated In Situ From Thiourea, Followed By Addition To The Enol Tautomer, Forming The Aminothiazole Backbone. This Novel Strategy Provides A Greener Alternative
