Abstract

En 中文
Methylenated cycloheptanoids are synthesized by formal (4+3) cycloadditions of dienes with epoxy allylsilanes as dienophiles in the presence of catalytic amounts of TESOTf. Intermolecular and intramolecular (4+3) cycloadditions with dienes including furans, cyclopentadiene, pyrroles, thiophenes, and benzenes proceeded to provide polycyclic adducts in moderate to good yields.
