A unified and efficient synthetic route for both tetraketide (1) and cryptorigidifoliol I (2) has been devised successfully from commercially available starting materials in 11 and 17 steps, with 16% and 11% overall yields, respectively. Highlights of the syntheses involved sequential Lewis acid-catalyzed highly regio- and diastereoselective allylations and intramolecular Mitsunobu lactonization.
Total syntheses of the resorcylic acid lactones paecilomycin F and cochliomycin C using an intramolecular loh-type α-allylation reaction for macrolide formation

Subjection of the resorcylic ester 16 to a Nozaki-Hiyama-Kishi reaction afforded the 12-membered lactone 17, while treatment of it under the Loh-type α-allylation conditions using indium metal gave the isomeric, 14-membered macrolide 18. Compound 18 was readily elaborated to the resorcylic acid lactone type natural products paecilomycin F and cochliomycin C.

Starting from different compounds, the syntheses of the four isomeric bicyclic acetals 17, 32, 36, and 40 - the title compounds - are described.One of these compounds is supposed to direct the attack of the striped ambrosia beetle Trypodendron lineatum Ol
