New versatile and selective methods for the syntheses of substituted amino- and methoxyphenolic anthraquinones (I-IV) based on fusion of cyanophthalides (V) and semiquinone aminals (VI, VII) under basic conditions are described. Fusion: 3-Cyanophthalides (V) react with substituted amino semiquinone aminals (VI, VII) under basic conditions to provide selectively a diverse array of substituted amino- and methoxyphenolic anthraquinones (I-IV).

A series of mono- and disubstituted phenoxypropanolamines, structurally related to practolol and acebutolol, has been synthesized and tested for β-adrenoreceptor blocking activity. Structure-activity relationships are discussed. The reasons for the lack of activity of compounds 3n and 4n have also been examined. The results suggest that the negative electrostatic potential above the phenyl ring of phenoxypropanolamines is essential for binding activity and point to the presence of an electropositive residue in the β-adrenoreceptor binding site.
