Synthetic Study of Phainanoids. Highly Diastereoselective Construction of the 4,5-Spirocycle via Palladium-Catalyzed Intramolecular Alkenylation

An efficient strategy to synthesize the western part of phainanoids is reported. The benzofuranone-based 4,5-spirocyclic motif is constructed diastereoselectively via a palladium-catalyzed intramolecular alkenylation. The computational study suggests that

Asymmetric syntheses of 8-oxabicyclo[3,2,1]octanes: A cationic cascade cyclization

High octane: A novel and practical syntheses of 8-oxabicyclo[3.2.1]octanes using a cationic cascade cyclization reaction has been developed (see scheme; TIPS=triisopropylsilyl). The diastereomer of the cyclization product isolated depends upon whether the acetal or aldehyde substrate is used. Copyright

A powerful new construction of complex chiral polycycles by an indium(III)-catalyzed cationic cascade

InI3 and InBr3 have been found to be effective catalysts for the π activation of C≡C bonds to initiate the conversion of chiral propargylic alcohols or silyl ethers to polycyclic products in excellent yields and with high stereoselectivity. The method has been applied to the synthesis of chiral fused hexacyclic ring systems with the creation of multiple new stereocenters. The power and scope of the method are illustrated by a variety of examples.

CYCLISATION PROCESS OF FORMING A MULTIPLE RING COMPOUND

The present invention relates to a cyclisation process of forming a multiple ring compound from an isoprenoid compound. The cyclisation process involves reacting the isoprenoid compound with an acetal initiator under conditions sufficient to form the multiple ring compound. The isoprenoid compound is contacted with an initiator an optionally with a catalyst. Cyclisation occurs by reaction of the initiator with the isoprenoid compound. Cyclic aceta compounds wherein the acetal forms part of 6-membered unsaturated ring are also defined.
