Vagh, Sandip Sambhaji; Hou, Bo-Jhih; Edukondalu, Athukuri; Wang, Pin-Ching; Lin, Wenwei published their research in Organic Letters in 2021. The article was titled 《Phosphine-Mediated MBH-Type/Acyl Transfer/Wittig Sequence for Construction of Functionalized Furo[3,2-c]coumarins》.HPLC of Formula: 673-22-3 The article contains the following contents:
A new method for the construction of functionalized furo[3,2-c]coumarins via MBH-type/acyl-transfer/Wittig reaction was reported. The current approach would open a new route for the simultaneous formation of two rings in a one-pot reaction which was accompanied by incorporation of a keto functionality on the furan ring by activating the terminal alkynoates with phosphine. Furthermore, this protocol could also be applicable to the internal alkynoates/propiolamides to generate the 2,3-disubstituted furo[3,2-c]coumarins/furo[3,2-c]quinolinones by excluding the acyl-transfer reaction. After reading the article, we found that the author used 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3HPLC of Formula: 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.HPLC of Formula: 673-22-3
