PROBLEM TO BE SOLVED: To provide new uses of (R)-2-hydroxy-2'-alkoxy-1,1'-binaphthalene and (S)-2-hydroxy-2'-alkoxy-1,1'-binaphthalene. SOLUTION: A cyclopropanecarboxylic acid can be easily put to optical resolution using (R)-2-hydroxy-2'-alkoxy-1,1'-binaphthalene represented by formula R-(I) or (S)-2-hydroxy-2'-alkoxy-1,1'-binaphthalene represented by formula S-(I). In the above formulas, A is methyl or ethyl. COPYRIGHT: (C)2008,JPO&INPIT
