Preparation of 3‐Alkylidenephthalides: Recent Advances

3-Alkylidenephthalides represent an important class of natural compounds which are also valuable synthetic precursors for the preparation of phthalides. While recent reviews reported the great interest of the phthalides in the field of medicinal chemistry, few reports are mentioning the recent progress for the synthesis of their unsaturated homologous in the position 3. So, the aim of this report is to present the latest progresses (since 2010 and until 2021) in the synthesis of 3-alkylidenephtalides
