Photoinduced cyclization of alkynoates to coumarins with N-Iodosuccinimide as a free-radical initiator under ambient and metal-free conditions
Wang, Zhihui,Li, Xuezhi,Wang, Lei,Li, Pinhua
, p. 1044 - 1051 (2019/01/25)
An efficient photoinduced strategy for the preparation of coumarins was developed. In the presence of N-iodosuccinimide (NIS) as a free-radical initiator and under LED (380–385 nm) irradiation and metal-free conditions, the reaction of alkynoates underwen
Synthesis of 4-arylcoumarins via palladium-catalyzed arylation/cyclization of ortho-hydroxylcinnamates with diaryliodonium salts
Yang, Yang,Han, Jianwei,Wu, Xunshen,Xu, Shujia,Wang, Limin
supporting information, p. 3809 - 3812 (2015/06/08)
The palladium-catalyzed arylation/cyclization of ortho-hydroxylcinnamate ester derivatives by using diaryliodonium(III) salts has been developed. With this method, 4-arylcoumarins were easily prepared in good to excellent yields under base-free conditions
A convenient solid-phase synthesis of coumarins by TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes
Tang,Li, Wen,Gao, Zhangyong
experimental part, p. 907 - 912 (2012/05/20)
TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes was performed using polystyrene-supported succinimidyl selenide as the selenium source. This catalytic process provides an efficient method for the regioselective synthesis of dihydrocou
