Badillo, Joseph J.,Silva-García, Abel,Shupe, Benjamin H.,Fettinger, James C.,Franz, Annaliese K.

supporting information; experimental part, p. 5550 - 5553 (2011/11/05)

The condensation cyclization between isatins and 5-methoxy tryptamine catalyzed by chiral phosphoric acids provides spirooxindole tetrahydro-β- carboline products in excellent yields (up to 99%) and enantioselectivity (up to 98:2 er). A comparison of cata
