Procedure

To gain entry into the 9-amino-1,2,3,4-tetrahydroacridin-1,3-diol series, i.e., to prepare diols of formula 15, an anthranilonitrile 10 is condensed with a 5-(phenyldialkylsilyl)-1,3-cyclohexanedione 11 to afford a 3-(oxocyclohex-1-enyl)-2-aminobenzonitrile 12, which is cyclized to a 9-amino-3-(phenyldialkylsilyl)acridinone 13 and, in turn, convened to a 9-amino-3-hydroxyacridinone 14 and reduced to a diol 15.
