benzoxazole and an amidopyridine provides an enantioselective receptor for sulfonylamino acids with chiral recognitions of up to 18. The structure of the complex between receptor 1 and the leucine triflate is known by X-ray analysis. The receptor racemic mixture can be suitably resolved through crystalization in the presence of leucine triflate as guest. Receptor 1 can be used for the enantioselective extraction
