ABSTRACT:
The present invention provides a method of preparing dimeric arylisoquinoline alkaloids by coupling two isoquinoline building blocks, which may be the same or different, together with a symmetrical or nonsymmetrical biaryl building block to form homodimers or heterodimers, including the antiviral michellamines. The present invention also provides new, medically useful homodimeric and heterodimeric arylisoquinoline compounds and derivatives thereof.
