| The C19 quassinoids are a small family of terpenoids exemplified by polyandrane. This paper will describe a synthetic approach in which a cycloetherification provides the E/C ring system, and a 5-exo-dig radical cyclization gives the B ring (1 → 2). Efforts to convert 2 and related structures to the polyandranes will also be described.
