Methods have been developed for the synthesis of 2,3′-biquinolines, their 1′,4′-dihydro derivatives, 3-pyrid-2-ylquinolines, and 3-pyrazin-2-ylquinoline based on the interaction of hetarylethylenes and vinyl butyl ether with imidoyl chlorides and Vilsmeie

Highly substituted purines were synthesized in good to high yields through a one-pot straightforward metal-free scalable method, using the Traube synthesis adapted to Vilsmeier-type reagents. From 5-amino-4-chloropyrimidines, new 9-aryl-substituted chloropurines and intermediates for peptide nucleic acid synthesis were prepared. Variant procedures allowing a rapid synthesis of ribonucleosides and 7-benzylpurine from 5-amidino-6-aminopyrimidines are also reported to illustrate the high potential of this versatile toolbox. This route appears to be particularly interesting in the field of nucleic acids for a direct and rapid access to various new 8-alkylpurine nucleosides.

Libraries of tricyclic 2-substituted 4-alkylamino-9-chloro-5,6-dihydropyrimido[5,4-d]benzazepines and tetracyclic 12-substituted 8-chloro-1,2,5,6-tetrahydro-4H-imidazo[1',2':1,6]pyrimido[5,4-d]benzazepines were synthesized as part of our research to develop new effective antiplatelet drugs. Several alkyl and aryl groups were used as substituents at the 2-position. Evaluation of the effects of the newly synthesized compounds on collagen-induced platelet aggregation revealed several promising antiplatelet candidates with potencies superior to aspirin.
