The pyridine alkaloid niphatesineC and its analogue norniphatesineC were prepared in a short and efficient way starting from commercially available 3‐iodopyridine and undec‐10‐yn‐1‐ol using a Sonogashirareaction as the key step. The resulting alkylpyridines were tested for antimicrobial activity against several bacteria and fungi. The cytotoxic activities were determined in the MTT assay against
