title: Concise, regioselective synthesis of the ABC tristetrahydropyran of thyrsiferol and venustatriol.
abstract: [structure: see text] The ABC tristetrahydropyran substructure 1 of the natural products thyrsiferol (2) and venustatriol (3) has been synthesized in 14 steps from farnesyl acetate, with effective control of all aspects of regio- and stereoselectivity in the formation of each tetrahydropyran ring.
