Himbacine is an alkaloid isolated from the bark of Australian magnolias. Himbacine has been synthesized using a Diels-Alder reaction as a key step.[1] Himbacine's activity as a muscarinic receptor antagonist made it a promising starting point in Alzheimer's disease research. The development of a muscarinic antagonist based on Himbacine failed but an analog is now in clinical trials as a thrombin antagonist.[2]
