Abstract:The domino annulation reactions of <i>o</i>‐aminotrifluoroacetophenone derivatives and MBH carbonates enabled by PPh<sub>3</sub> have been reported, which provide a series of tetrahydrofuro[3,2‐b]indolines containing a CF<sub>3</sub>‐substituted tetrasubstituted carbon stereocenters in yields of 74 to 95% and >20:1 dr. In this process, MBH carbonates were used as C1/C3 synthons. The MTT assay shows that the products exhibit the activity of inhibitory effect on proliferati… Show more
