The development of a rapid, highly efficient, and one-pot synthesis of C3-α-prenylated oxindoles with simple reagents is described. The process is based on zinc-mediated α-regioselective prenylation of 3-acylidene-oxindole with commercially available pren
Squaramide-Catalyzed Enantioselective Cascade Approach to Bispirooxindoles with Multiple Stereocenters
Zhao, Bo-Liang,Du, Da-Ming
supporting information, p. 3992 - 3998 (2016/12/30)
A bifunctional squaramide-catalyzed Michael/Michael cascade reaction for the construction of spirotetrahydrofuran bispirooxindoles was developed. The products were obtained in moderate to excellent yields with excellent diastereo- and enantioselectivities
