Abstract

We examined the Lewis acid catalysis of chiral Al(salalen)X complexes and found that complex 1b (X = Br) serves as an efficient catalyst for the Friedel-Crafts reaction of indole with N-[(E)-alkenoyl]oxazolidin-2-ones. High enantioselectivity (up to 98% ee) was obtained under the optimized conditions.
