Synthetic Photochemistry. Part 44. Total Synthesis of Ceroplastol II and Albolic Acid, 5-8-5-Membered Tricyclic Sesterterpenoid Insect Wax Constituents, via Stereocontrolled Silyloxy-Cope Rearrangement with a Normally Disfavoured Transition State

To a 1,5-diene, prepared by CrCl2-mediated condensation of two iridoid synthons, was appended a lactol moiety, which was subjected to a stereocontrolled silyloxy-Cope rearrangement to give, via a normally disfavoured boat transition geometry, a thermolysa

Total Synthesis of Albolic Acid and Ceroplastol II, 5-8-5-Membered Tricyclic Insect Sesterterpenoids, via a Lactol-Regulated Silyloxy-Cope Rearrangement

Optically active albolic acid and ceroplastol II, 5-8-5-membered tricyclic sesterterpenoids, were stereoselectively synthesised from two C10 synthons (iridoids) via CrCl2-condensation, lactol-regulated silyloxy-Cope rearrangement with a normally disfavour
