The synthesis of siloles with substitution patterns that are continuative toward natural product synthesis are described. Their reactivity in Diels−Alder chemistry was explored through thermal, Lewis acid, and high-pressure reactions. Furthermore, bicyclic adducts were oxidatively cleaved to reveal a highly functionalized cyclohexene core.
