A stereoselective total synthesis of (±)-erythrodiene
摘要:
Erythrodiene, a unique spirobicyclic sesquiterpene hydrocarbon from the Caribbean gorgonian cord Erythropodium caribaeorum, has been synthesized from 4-isopropylcyclohexanol in 8-steps and approximately 16% overall yield. The synthesis features a stereoselective intramolecular carbomercuration reaction as the key step.
Ring out the old: The cycloisomerization of alkynylsilylenolethers proceeds at ambient temperature under the mild conditions of silver catalysis (see scheme). Mono‐ or bicyclic spiro compounds can be obtained by 5‐exo‐dig reactions. Trapping the vinyl silver species with an iodide source, such as N‐iodosuccinimide (NIS), afforded the alkenyl iodide derivatives.
