Abstract
Catalytic oxidative cyclisation reactions have been employed for the synthesis of the E and F rings of the complex natural product target pectenotoxin 4. The choice of metal catalyst (cobalt- or osmium-based) allowed for the formation of THF rings with either trans or cis stereoselectivity. Fragment union using a modified Julia reaction then enabled the synthesis of an advanced synthetic intermediate containing the EF and G rings of the target.

Abstract
Concepts: The formation of stereochemically defined bis-THF units through a double cyclization and a hydride-shift-initiated route to spiroketals is described (see scheme; Xc=chiral auxiliary). The resulting sequence has been used in a synthesis of the C1-16 fragment of the naturally occurring antitumor agent pectenotoxin-4.
