Assembling polycyclic bisguanidine motifs resembling batzelladine alkaloids by double tethered Biginelli condensations.
[reaction: see text] Double tethered Biginelli condensations furnish linked polycyclic bisguanidines or bisureas. Alteration of the bis-beta-ketoester component allows bispolycyclic guanidine motifs to be constructed that resemble natural batzelladine alkaloids or have novel linkages.
