Tagetitoxin is an unusually densely functionalized natural product, consisting of an unprecedented oxathiabicyclo[3.3.1]nonane ring system possessing acetate, phosphate, amide, carboxylic acid, and amine groups with six contiguous asymmetric centers. A fully functionalized core structure of tagetitoxin was synthesized from tri-O-acetyl-D-galactal in a highly stereoselective manner.
