Indenes and their derivatives widely exists in natural world, and some of them bearing multi-functional groups are very potential to become the lead compounds in drug because of their important bioactivities. In particular, asymmetric syntheses of indenes have attracted the extensive attention of organic chemists. Recently, many synthetic methods of them have been reported, including resolution of racemic mixture, syntheses of chiral auxiliary or substrate's induction, as well as chiral catalytic synthesis. In this review, we summarize the asymmetric syntheses of these compounds, and focus on the transition metal-catalyzed and organocatalytic asymmetric reaction. Finally, the further research on this field is also discussed.
