Abstract

12 been reported so far, for example, resolution by inclusion complex formation with optically active methyl m-tolyl sulfoxide'and by fractional recrystallization of the cinchonine salt of the cyclic phosphoric acid derivative of ll. S However, these are not efficient preparative methods for obtaining optically active 11 in bulk, because preparation of the optically active methyl m-tolyl sulfoxide is not easy and cinchonine is very expensive. ...
