In 2019,Organic Letters included an article by Yoo, Huen Ji; Youn, So Won. Recommanded Product: 673-22-3. The article was titled 《Zn(II)-Catalyzed One-Pot Synthesis of Coumarins from Ynamides and Salicylaldehydes》. The information in the text is summarized as follows:
Substituted coumarins and iminocoumarins were prepared regioselectively by cyclocondensation of ynamides (particularly N-alkynyl-N-methylmethanesulfonamides) with salicylaldehydes, o-hydroxyphenyl ketones, and o-aminophenyl ketones in the presence of ZnBr2. Generation of an ynamide in situ from 1-bromo-2-phenylethyne and N-methylmethanesulfonamide allowed the recycling of the methanesulfonamide through five cycles; the presence of coumarin did not inhibit the copper-catalyzed amination of the bromoalkyne. The experimental part of the paper was very detailed, including the reaction process of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Recommanded Product: 673-22-3)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is employed in the synthesis of Schiff base ligand. It is applied as a reactant in the synthesis of LPA1R antagonists used in the inhibition of LPA-induced proliferation and contraction of normal human lung fibroblasts. Also used in the synthesis of tyrosine kinase 6 proteinase inhibitors.Recommanded Product: 673-22-3
