초록
Novel binol receptor with pyrrole-2-carboxamide moiety and its analogues have been designed, synthesized, and used to enantioselectively recognize 1,2-aminoalcohols via multiple hydrogen bonding. The pyrrole-based binol receptor showed the highest enantioselectivity among the four receptors as determined by the H-1 NMR. The DFT calculation strongly supports complementary hydrogen bonding between alcoholic -OH and Pyrrolyl groups. (c) 2008 Elsevier Ltd. All rights reserved.
