, (2020)
An efficient method for the synthesis of (Z)-3-ylidenephthalides is reported in moderate to high yield with AlCl3 as catalyst. Different substrates of the 2-acylbenzoic acids are well performed in the Z/E selectivity. This method is highlighted
Use of Imidazo[1,5-a]pyridin-3-ylidene as a Platform for Metal-Imidazole Cooperative Catalysis: Silver-Catalyzed Cyclization of Alkyne-Tethered Carboxylic Acids
